    • The invention relates to a process for making modified polybutylene terephthalate random copolymers from a polyethylene terephthalate component. In one embodiment, the invention relates to a two step process in which a 1,4-butane diol component reacts with a polyethylene terephthalate component under conditions that depolymerize the polyethylene terephthalate component into a molten mixture and the molten mixture is placed under subatmospheric conditions that produce the modified polybutylene terephthalate random copolymers. In another embodiment, the invention relates to a three step process in which a diol component selected from the group consisting of ethylene glycol, propylene glycol, and combinations thereof reacts with a polyethylene terephthalate component under conditions sufficient to depolymerize the polyethylene terephthalate component into a first molten mixture; and where the first molten mixture is combined with 1,4-butane diol under conditions that create a second molten mixture that is subsequently placed under subatmospheric conditions that produce the modified polybutylene terephthalate random copolymers. The invention also relates to compositions made from processes of the invention.

    • The invention relates to a composition comprising a modified, random copolyetherester containing a modified, random polybutylene 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 is derived from a polyethylene terephthalate component and polyalkylene oxide glycol, and contains polyalkylene oxide and at least one residue derived from the polyethylene terephthalate component. Advantageously, 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) polybutylene terephthalate derived from a monomer component selected from the group consisting of terephthalic acid, isophthalic acid, alkyl esters of terephthalic acid, hydroalkyl esters of terephthalic acid, alkyl esters of isophthalic acid, 1,4-butanediol, (2) polyalkylene oxide glycol, and (3) combinations thereof. The invention also relates to articles made from the composition, methods of making the composition. The invention also relates to copolyetherester containing: a modified, random polytrimethylene terephthalate copolymer blocks, articles made from the compositions, and methods for making such materials.
