Mx. Xu et al., STUDY ON PHASE BEHAVIOR-IMPACT STRENGTH RELATIONSHIP OF UNSATURATED POLYESTER POLYURETHANE HYBRID POLYMER NETWORK, Polymer international, 38(2), 1995, pp. 205-209
The phase behavior of a hybrid polymer network (HPN) composed of poly[
(propylene glycol maleate)-co-(propylene glycol phthalate)] crosslinke
d with styrene and polyester-urethane crosslinked with methylene-bis-o
rthochloroaniline was examined. The correlation between phase separati
on and impact strength of the HPNs is discussed. The composition of HP
Ns has an effect on their properties.
