| Abstract: | A series of block copolyesters based on poly(ethylene terephthalate co isophthalate) poly(ethylene glycol)(PEIT PEG)was prepared by direct esterification poly condensation process. The effects of components together with their molecular weight and contents on copolymerization time, copolymerization efficient and the intrinsic viscosity of the block copolyesters were discussed, by which the spinning grade molecular weight and contents of PEG were concluded. |
