V. Mishra et al., INTERPENETRATING POLYMER NETWORKS BASED ON THERMOPLASTIC POLYURETHANES (TPUS) AND CIS-1,4-POLYISOPRENE, Journal of applied polymer science, 53(11), 1994, pp. 1425-1434
Semi-interpenetrating polymer networks based on two elastomers, cis-1,
4-polyisoprene (PI) and thermoplastic polyurethane elastomers (TPUs) w
ere prepared in varying compositions. The PI component was cross-linke
d using peroxide initiators. Modulus and mechanical properties were in
vestigated as a function of composition and temperature. Slight synerg
isms were observed in mechanical properties, particularly for composit
ions containing 10% PI by weight. Little or no molecular mixing is sho
wn by differential scanning calorimetry (DSC) for these two-phase mate
rials. (C) 1994 John Wiley & Sons, Inc.
