ABSTRACT:
The present invention is directed to the combined use of first and second fatty acid amides to improve the softness of a thermoplastic polymer construct. A combination of fatty acid amides is provided in the blend ratio of about 10 to 90 percent by weight of a first fatty acid amide and 90 to 10 percent by weight of a second fatty acid amide. The first and second fatty acid amides are compounded into a thermoplastic polymer carrier resin and, preferentially, produced as concentrate pellets containing 0.5 to 75 percent by weight total fatty acid amide loading. The concentrate pellets are introduced into a thermoplastic polymer base, to form a thermoplastic resin, at a letdown level in the range of about 1 to 15 percent, with the range of 2 to 10 percent being preferred, and the range of 3 to 6 percent being most preferred.
