The present invention relates to novel polymeric compositions which are thermoplastic and have high softening temperatures and low permeability to gases and, more particularly, pertains to high softening compositions which have high flexural strengths and flexural modulus.
The novel polymeric compositions are essentially of an olefinically unsaturated nitrile, an N-vinyl imide and indene or coumnarone.
The novel polymeric products of the present invention are prepared by polymerizing an olefinically unsaturated nitrile, such as acrylonitrile, and an N-vinyl imide, such as N-vinyl succinimide, and indene or coumarone.
The olefinically unsaturated nitriles useful in this invention are the alpha, betaolefinically unsaturated mononitriles having the structure CH 2 =C-CN wherein R is l R hydrogen, a lower alkyl group having from 1 to 4 carbon atoms, or a halogen Such compounds include acrylonitrile, alpha-chloroacrylonitrile, alpha-fluoroacrylonitrile, methacrylonitrile and ethacrylonitrile The preferred olefinically unsaturated nitrile is acrylonitrile.
The N-vinyl imides include N-vinyl succinimide, N-vinyl glutarimide, and N-vinyl phthalimide Most preferred is N-vinyl succinimide.
Of indene ( 1-H-indene) and coumarone 45 ( 2,3-benzofuran), indene is more preferred.
The polymeric compositions of the present invention can be prepared by any of the known general techniques of polymerization, including the bulk polymerization, solution 50 polymerization, and emulsion or suspension polymerization techniques by batch, continuous or intermittent addition of the monomers and other components The preferred method is by polymerisation in 55 aqueous medium, preferably by emulsion or suspension techniques The polymerization is preferably carried out in an aqueous medium in the presence of a free-radical generating polymerization initiator and preferably in 60 the presence of an emulsifier, at a temperature of from 0 to 100 C in the substantial absence of molecular oxygen.
The polymeric compositions according to the present invention are those resulting from 65 the polymerization of (A) from 30 to 90 % by weight of at least one nitrile having the structure CH 2 =C-CN wherein R has the forel R 70 going designation, (B) from 5 to 55 % by weight of an N-vinyl imide and (C) from 1 to % by weight of at least one of indene and coumarone wherein the given percentages of (A), (B) and (C) are based on the combined 75 weight of (A), (B) and (C).
Particularly the present invention can be illustrated by the polymerization of a mixture of acrylonitrile, N-vinyl succinimide, and indene to produce a product having except 80 r_ in ( 11) 1 570 447 1 570 447 ionally good impermeability to gases and vapours, and excellent ASTM heat-distortion temperature Preferably, the acrylonitrile, Nvinyl succinimide, indene monomer component should contain 35 to 70 % by weight of acrylonitrile, S to 50 % by weight of N-vinyl succinimide and 5 to 25 % by weight of indene.
The novel resins of the present invention are thermoplastic materials which can be thermoformed into a wide variety of useful articles in any of the conventional ways employed with known thermoplastic materials, such as by extrusion, milling, moulding, drawing and blowing The polymeric products of this invention have excellent solvent resistance, and their high softening temperatures make them extremely useful engineering thermoplastics for use in the construction industry as well as in the packaging industry, and they are particularly useful in the manufacture of bottles, film, sheet, laminates with other plastics, and other kinds of containers and wrappings for liquids and solids.
In the following illustrative examples, the amounts of ingredients are expressed in parts by weight unless otherwise indicated.
EXAMPLE 1
A An aqueous emulsion polymerization was carried out using the following ingredients and procedure:
Ingredient water Gafac RE-610 emulsifier (Registered Trade Mark) acrylonitrile N-vinyl succinimide indene n-dodecyl mercaptan potassium persulphate Parts 250 2.5 0.1 0.3 A mixture of R-0-(CH 2 CH 2 0-)n PO 3 M 2 and lR-0-(CH 2 CH 2 0-)n l 2 PO 2 M wherein N is a number from 1 to 40, R is an alkyl or alkaryl group and preferably a nonyl phenyl group, and M is hydrogen, ammonia or an alkali metal, which composition is sold by GAF Corporation.
The polymerization was carried out at 60 C with stirring under a nitrogen atmosphere for 16 hours A conversion of monomers to polymer which was greater than 60 % of theory was obtained The resin was isolated by coagulation of the latex followed by washing and drying of the solid resin This resin was found to have the following properties:
ASTM heat-distortion 114 C temperature ( 264 psi) flexural strength 12 8 x 103 psi flexural modulus 6 2 x 105 psi B A polymer which is outside the scope of this invention was prepared by the procedure of A of this example using 30 parts of inene and no N-vinyl succinimide The resulting resin was found to have the following properties:
ASTM heat-distortion 114 C temperature flexural strength 4 95 x 103 psi flexural modulus 5 50 x 105 psi EXAMPLE 2
The procedure of Example 1 A was repeated using 60 parts of acrylonitrile, 20 parts of Nvinyl succinimide and 20 parts of indene The resulting resin was found to have the following properties:
ASTM heat-distortion 128 C temperature flexural strength 10 9 x 103 psi flexural modulus 6 27 x 105 psi EXAMPLE 3
The procedure of Example 1 A was repeated using 50 parts of acrylonitrile, 35 parts of Nvinyl succinimide and 15 parts of indene The resulting resin was found to have the following properties:
ASTM heat-distortion 136 C temperature flexural strength 14 4 x 103 psi flexural modulus 6 59 x 105 psi ASTM oxygen trans 0 4 cc/mil/100 mission rate inches 2 /24 hours / atmosphere 95 EXAMPLE 4
The procedure of Example 1 A was repeated using 40 parts of acrylonitrile, 45 parts of Nvinyl succinimide and 15 parts of indene The resulting resin was found to have the following properties:
