Abstract
1,220,310. Polyurethanes. FARBENFABRIKEN BAYER A.G. 17 Oct., 1969 [17 Oct., 1968; 8 Aug., 1969], No. 50891/69. Heading C3R. [Also in Division C2] Polyurethane elastomers are produced by reacting a compound containing at least two hydroxyl groups and having a molecular weight of 800-5000 with a diisocyanate employing as a chain-extender an aromatic diamine containing an ester group linked directly to an aromatic nucleus wherein the amino groups are in the meta- and/or paraposition to the ester group and a fluorine, chlorine or bromine atom or a C 1-4 alkoxy substituent is in the ortho-position to at least one amino group.
