Abstract

The invention is directed to plasticized compositions comprising esters of terephthalic acid, particularly PVC compositions.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Serial No. 61 / 138,798 filed December 18, 2008, the disclosure of which is incorporated by reference in its entirety. technical field [0003] The present invention relates to polymer compositions comprising terephthalic acid esters, more particularly, but not limited to, PVC compositions plasticized with C5-C7 alcohol esters of terephthalic acid. Background technique [0004] Plasticizers are incorporated into resins (usually plastics or elastomers) to improve the resin's flexibility, processability, or expandability. The largest use of plasticizers is in the production of "plasticized" or flexible polyvinyl chloride (PVC) products. Typical applications of plasticized PVC include films, sheets, hoses, coated fabrics, wire and cable insulation and jacketing, toys, flooring materials such as vinyl sheet flooring or vinyl floor tiles , adhesives, sealants, inks and medical products...
