ABSTRACT:
Azido formyl or azido sulfonyl compounds are provided by compounds of the formula R(CH.sub.2).sub.m X wherein R represents a fluorocarbon or an alkoxy alkyl chain and X represents a sulphonazide or azidoformate group and m is an integer greater than 1. The R group may be C.sub.2 to C.sub.12 linear or branched alkyl, C.sub.2 to C.sub.12 linear or branched alkoxy substituted C.sub.2 to C.sub.12 alkyl, or C.sub.2 to C.sub.12 linear or branched fluoroalkyl. The group (CH.sub.2).sub.m is C.sub.2 to C.sub.10 linear or branched alkylene. These materials upon thermolysis give rise to a reactive intermediate which adds to and protects polymeric substrates such including polyethylene, polypropylene, polystyrene, the natural rubbers, polyamides, polyesters, polybutadienes, polyisoprenes, butadiene-isoprene copolymer, butyl rubber, ethylene-propylene copolymer, ethylene-propylene-dicyclopentadiene terpolymer, and the like, as well as blends thereof.
