STUDIES ON POLY(ETHYLENE TEREPHTHALATE)-POLY(TETRAMETHYLENE ETHER) MULTIBLOCK COPOLYMER.Ⅱ.THE MOLAR SEGMENT MASS AND MOLAR MASS

Received Date: 23 March 1990

The molar segment mass, weight-average molar mass, and molar mass distribution of a poly-(ethylene terephthalate)-poly (tetramethylene ether) multiblock copolymer sample were determined by the methods of proton nuclear magnetic resonance, low angle laser light scattering, and gel permeation chromatography.
