## Abstract **Summary:** Coumarin containing poly(ethylene glycol) monols and diols were prepared in a telechelic fashion using quantitative end group esterification. The coumarin modified poly(ethylene glycol) monols and diols were solution cast into films (1 to 15 ฮผm) and chain extended via the d

Poly(ethy1ene terephthalate) copolymers were prepared by melt polycondensation of dimethyl terephthalate and excess ethylene glycol with 10- 40 mol% (in feed) of poly(ethy1ene glycol) (E) and poly(tetramethy1ene glycol) (B), with molecular weight (MW) of E and B 200-7500 and 1000, respectively. The
A comparison is made of the chain conformational distribution of hydroxyterminated poly(propylene glycol) (PPG) and poly(ethylene glycol) (PEG) with their methoxy-terminated derivatives. The significant end-group dependence on the glass transition temperature in PPG was observed by differential scan
