Patent number: H1987Abstract: The use of a specified molecular weight range of poly(alkylene ether)s, such as poly(ethylene glycol) (PEG), poly(tetramethylene glycol) (PTMG), and poly(propylene glycol) (PPG), and end-capped poly(alkylene ether)s, as plasticizers for polyesters such as poly(ethylene terephthalate) (PET), poly(propylene terephthalate) (PPT), poly(butylene terephthalate) (PBT), poly(ethylene naphthalate) (PEN), and poly(1,4-cyclohexanedimethylene terephthalate) (PCT), that are non-volatile during drying processes as well as during melt processing. Such poly(alkylene ether)s and end-capped poly(alkylene ether)s decrease the melt viscosity of the polymer matrix and depress the glass transition temperature, and thereby improve the processability of polyesters.Type: GrantFiled: April 22, 1999Date of Patent: August 7, 2001Assignee: Eastman Chemical CompanyInventors: Andrew E.
