Interpenetrating polymer networks based on thermoplastic polyurethanes (TPUS) andcis‐1,4‐polyisoprene

摘要

AbstractSemi‐interpenetrating polymer networks based on two elastomers,cis‐1,4‐polyisoprene (PI) and thermoplastic polyurethane elastomers (TPUs) were prepared in varying compositions. The PI component was cross‐linked using peroxide initiators. Modulus and mechanical properties were investigated as a function of composition and temperature. Slight synergisms were observed in mechanical properties, particularly for compositions containing 10 PI by weight. Little or no molecular mixing is shown by differential scanning calorimetry (DSC) for these two‐phase materials. © 1994 John Wiley
