摘要：
Polyurethane propylene glycol(PPG2000) and 2, 4-toluene diisocyanate (TDI) were used to synthesize a polyurethane prepolymer, which was capped with hydroxyethyl methacrylate (HEMA) to obtain a vinyl terminated urethane resin (VTUR). Styrene (St) as cross-linking monomer was added. Elastomers with different styrene contents were prepared with two curing agents, cumene hydrogen peroxide (CHP) and methyl ethyl ketone peroxide (MEKP). The synthesis of VTUR was analyzed, the influence of styrene content on the viscosity of the resins, and the influence of the amount of styrene and the type of curing agent on the damping and mechanical properties of the elastomers were also studied. The results show that VTUR was successfully synthesized and the addition of styrene decreases the viscosity of the resins; with the increase of styrene content, the damping peak of the elastomer gradually increases, and the peak temperature shifts to high temperature; the mechanical strength is increased. The elastomers made with CHP curing agent have better damping properties. © 2021, Editorial Board of Polymer Materials Science & Engineering. All right reserved.
