Abstract
The invention relates to a composition comprising a modified, random copolyetherester containing a modified, random polytrimethylene terephthalate copolymer block that is derived from a polyethylene terephthalate component selected from the group consisting of polyethylene terephthalate and polyethylene terephthalate copolymers and combinations thereof; and contains at least one residue derived from the polyethylene terephthalate component; and a polyalkylene oxide copolymer block that contains polyalkylene oxide and at least one residue derived from the polyethylene terephthalate component. The composition has a modulus of elasticity that is at least 80%, as compared to the modulus of elasticity of a copolyetherester derived from (1) polytrimethylene terephthalate derived from a monomer component selected from the group consisting of terephthalic acid, isophthalic acid, alkyl esters of terephthalic acid, hydroxyalkyl esters of terephthalic acid, alkyl esters of isophthalic acid, 1,3-propane diol, (2) polyalkylene oxide glycol, and (3) combinations thereof.
