POLYBUTADIENE COMPOSITIONS, METHODS AND ARTICLES

摘要

The invention relates to an elastomeric composition, comprising by weight : a)
100 parts of one or more elastomers, b) from 1 to 40 parts of one or more
coagents comprising one more terminally- functional alkoxylated polybutadiene
(meth)acrylates c) from 0 to 200 parts of a filler material. More
particularly, terminally-functional low molecular weight alkoxylated
polybutadiene (meth)acrylates of Formula (I) : wherein R is H, Me, Et or C6H5;
R'' is H or Me; R" is H or Me; n = 1 to 100; and Z = 1 to 3, may be used to
improve the physical properties of elastomeric compositions cured in the
presence of at least one free-radical generating compound selected from
peroxides, percarbonates or azo compounds. The elastomers are natural or
synthetic or mixtures thereof. Reinforcing fillers may also be present.
