摘要：

A polyester copolymer is produced by step-growth polymerization of neopentyl glycol (50 mol%), trimethylol propane (1%), terephthalic acid (45%) and adipic acid (5%) and its microstructure is characterized by gel permeation chromatography and matrix-assisted laser desorption ionization mass and tandem mass spectrometry. The combination of these analytical methods is shown to yield detailed insight about the composition, end groups, molecular weight, and sequence of the product. (C) 2002 Elsevier Science B.V.
