Abstract
1348213 Vinyl ether/cyclic polyene copolymers SNAM PROGETTI SpA 19 July 1972 [31 July 1971] 33854/72 Heading C3P A copolymer of a vinyl-ether and a cyclic polyene containing at least two carbon-carbon double bonds which are conjugated, which copolymer has a molecular weight higher than 50,000 and has a vinyl-ether content higher than 80% (calculated on a molar basis) may be prepared by polymerizing the cyclic polyene with the vinyl-ether in the presence of a Friedel- Crafts catalyst. In the examples vinyl-isobutyl ether, vinyl-2-chloro-ethyl ether, vinyl-n-butyl ether, vinyl ethyl ether, cyclopentadiene, methyl-cyclopentadiene, 1-isopropylidene-dicyclopentadiene, dehydrodicyclopentadiene and 1 – isopropylidene – 3a,4,7,7a – tetrahydroindene are copolymerized in the presence of CH 2 Cl 2 , BF 3 .OEt 2 , toluene, AlEtCl 2 , CH 3 Cl, TiCl 4 , C 6 H 5 NO 2 , AlCl 3 + TiCl 4 , PF 5 and Al 2 (SO 4 ) 3 .- H 2 SO 4 . The copolymers are vulcanized using stearic acid, ZnO, sulphur, 2-mercapto-benzothiazole, tetramethyl-thiuramdisulphide and phenyl-#-naphthylamine.
