FILLED BLENDS OF TUBULAR REACTOR PRODUCED ETHYLENE/ALKYL ACRYLATE COPOLYMERS MODIFIED WITH ORGANIC ACIDS

摘要

Disclosed are filled and plasticized blends of tubular reactor produced ethylene/alkyl acrylate copolymers modified with organic acids, consisting essentially of (a) from about 1 to about 50% by weight of at least one tubular reactor produced ethylene/alkyl acrylate copolymer; (b) from about 1 to 20 percent by weight of at least one plasticizer selected from the group consisting of processing oils, epoxidized oils, polyesters, polyethers, and polyether esters; (c) from about 40 to about 90% by weight of filler; (d) from about 0.05 to about 5% by weight of at least one organic acid or acid derivative selected from the group consisting of saturated or unsaturated mono- and polycarboxylic acids having from 6 to 54 carbon atoms, and mixtures thereof; and optionally (e) from 0 to about 5% by weight of tackifier. Also disclosed are sound management sheets that comprise these compositions. Also disclosed are carpets, especially automotive carpets, having backside coatings comprising these compositions.
