Patent ID: 7238313

Claim:
A method for manufacturing a thermoplastic construct, comprising; a. providing a thermoplastic polymer base composition; b. providing a first fatty acid amide; c. providing a second fatty acid amide, said second fatty acid amide having a different fatty acid chain composition than said first fatty acid amide; d. providing a third performance-modifying additive; e. blending said thermoplastic polymer base and said third performance-modifying additive to provide a thermoplastic polymer base composition/performance-modifying additive composition; f. blending said first and second fatty acid amides into said thermoplastic polymer base composition/performance-modifying additive composition to provide a thermoplastic blend, said first fatty acid amide comprising between 10 to 90 percent by weight of the overall fatty acid amide present in said thermoplastic blend, said second fatty acid amide comprising between 90 to 10 percent by weight of the overall fatty acid amide present in said thermoplastic blend; and g. extruding said thermoplastic blend as a thermoplastic construct, said thermoplastic construct exhibiting an improved softness as compared to a thermoplastic construct consisting of said thermoplastic polymer base.
