ETHYLENE-SILANE TELOMER-COPOLYMERS

摘要

Telomer-copolymers of ethylene and silane monomers which have the formula: < IMG > wherein: x is 0 or 1; y is 0 or 1; R1 is H or an aliphatic radical having from 1 to 5 carbon atoms, R2 is a saturated aliphatic radical having from 1 to 10 carbon atoms or an aryl radical having no more than two aromatic rings; m is from 1 to 5; n is from 1 to 5; v is from 1 to 3; R3 is H or an aliphatic radical having from 1 to 4 carbon atoms. R is H when x = 0. The copolymers have a number average molecular weight of from 500 to 10,000 and from 0.1 to 70% by weight of the silane comonomer moiety. Each copolymer is capped by a telomer chain transfer agent.
