COMPOSITIONS COMPRISING POLY(TRIMETHYLENE TEREPHTHALATE) AND THERMOPLASTIC POLYOLEFIN AND PROCESSES USING THE COMPOSITIONS.

摘要

This invention pertains to compositions and processes suitable for recycling post-consumer carpet tiles that comprise poly(trimethylene terephthalate) fibers and thermoplastic polyolefin backings. The compositions disclosed herein comprise poly(trimethylene terephthalate) and thermoplastic polyolefins, compositions which may or may not be mineral filled. Strong tough articles can be prepared by molding or extrusion of typical commercially available carpet tiles when combined with additional amounts of thermoplastic polyolefin, whether filled or unfilled.
