S. Basu et al., THERMAL-DEGRADATION CHARACTERISTICS OF POLY[POLY(ETHYLENE GLYCOL)] PHOSPHATES, Journal of applied polymer science, 58(3), 1995, pp. 523-526
Thermal degradation characteristics of some poly[poly(ethylene glycol)
] phosphates (PPEGP) based on ethylene glycol (PEGP), an equimolar mix
ture of ethylene glycol and trigol (PETP), digol (PDGP), and trigol (P
TGP) have been studied by combined differential thermal and thermograv
imetric analyses (DTA/TGA). It has been shown that, in spite of their
structural similarities, the PPEGPs do not conform to any generalized
degradation pattern. Local strains in the crosslinked network and the
possible intranetwork topographic interferences due to crossovers, ent
anglements, and varying lengths of polyoxyethylene link units are beli
eved to play a pivotal role in the thermal degradation of individual P
PEGPs. (C) 1995 John Wiley & Sons, Inc.
