| abstract | 1362173 Photodegradable polyamides GOVERNING COUNCIL OF THE UNIVERSITY OF TORONTO 27 April 1971 [27 April 1970] 20102/70 Heading C3R A thermoplastic condensation polymer which is a polyamide of a diamine and a dicarboxylic acid or functionally equivalent derivative thereof contains in the main polymeric chain units where R is C 1-12 alkyl, aryl, alkaryl or alkenyl and R<SP>1</SP> is H or C 1-6 alkyl, providing 0À01 to 15 wt. per cent of ketone carbonyl based on the total polymer and preferably has a Tg below 30‹ C. They may be formed by including a diamine and/or a diacid in the polymer-forming reactants. In examples polymers are made from hexamethylene diamine and γ-acetyl pimelic dichloride, a mixture thereof with adipyl, 3-methyl adipyl or sebacyl chloride, or a mixture of γ-benzoyl pimelic dichloride and sebacyl chloride. Uses.-The polymers are stated to be photodegradable under the action of the U.V. light of the sun but to have indefinite storage life indoors and thus to be suitable for disposable packaging material. |
