    摘要： The color of polyamides of bis(aminophenyl)sulphones and Alpha , omega -polymethylene dicarboxylic acids having from six to 16 carbon atoms in all, or mixtures of these acids with up to 25 mole percent of one or more other dicarboxylic acids, may be improved by replacing from 4 to 20 mole percent of the bis(aminophenyl)sulphone with a linear or branched alkylene diamine having the structure NH2CH2(CR1R2)mCH2NH2 where each R1 and R2 is hydrogen or an alkyl group having up to four carbon atoms and m is from 0 to 10 inclusive.

    摘要： Moulding composition in particulate form comprising at least one prepolymer containing urethane groups and having the structure

    and hereinafter referred to as the vinyl-ended prepolymer, in which R1 and R2 are each divalent organic groups at least one of which contains at least one cyclic group in the chain and are such that in said structure there are not more than 20 atoms in the chain between each cyclic group, n is a whole number of from 1 to 20, and when n is one and only R2 contains a cyclic group in the chain there are no more than 20 atoms in the chain between the cyclic group in R2 and the nitrogen atom attached to the group X, R3 is hydrogen or a hydrocarbyl group and X is a divalent group are useful in forming articles such as films.
