摘要：

Polyesters from dimethyl terephthalate, ethylene glycol, poly (ethylene glycol) and 4,4'-bis(carbomethoxy)-stilbene were synthesized via a thermal transesterification reaction. The assignment of proton frequencies was facilitated by 2-D n.m.r. techniques. The presence of ethylol end groups and the occurrence of a cis to trans stilbene monomer isomerization were observed and are reported herein.
