1279563 Coating HERCULES Inc 1 June 1970 [18 July 1969] 26380/70 Heading B2E [Also in Divisions B5 C2 and C3] Polymers may be bonded to a primed substrate selected from siliceous materials, metals and other polymers using an epoxy-azido compound of general formula where R is a polyvalent organic radical, R' is H, alkyl, cycloalkyl, aryl or aralkyl, or together with the epoxidised carbon atoms forms part of a cyclo-alkyl radical in which the group -R-(A-N 3 ) m is a substituent, A is -O.CO- or -SO 2 - and n and m are integers from 1-100. In example 8 polyethylene terephthalate tyre cord was coated with the epoxidation product of the azidoformate of the triallyl ether of pentaerythritol and then coated with a conventional latex adhesive which was then vulcanised with a rubber tire stock. |
