POLYBUTADIENE COMPOSITIONS, METHODS, AND ARTICLES

摘要

Terminally-functional low molecular weight alkoxylated polybutadiene (meth)acrylates are 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. Preferred alkoxylated polybutadiene (meth)acrylates are 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.
