METHOD FOR PREPARING MODIFIED POLY (1,3-PROPANEDIOL TEREPHTHALATE)
Document Type and Number:
WIPO Patent Application WO/2011/131057
Kind Code:
A1
Abstract:
A method for preparing modified poly (1, 3-propanediol terephthalate) is disclosed. The method comprises adding linear polyester with average molecular weight of 800~3000 and polyethylene glycol with average molecular weight of 200~2000 into polymeric monomers before polymerization, wherein the linear polyester is a polymer obtained by reaction of C3~C10 straight chain aliphatic dicarboxylic acid or 1,4-cyclohexane diformic acid with C2~C10 straight chain aliphatic diol or 1,4-cyclohexane dimethanol; the linear polyester is 0.5%~6% of the mass of polymeric monomers; the polyethylene glycol is 0.5%~8.5% of the mass of polymeric monomers.
