Abstract The dependence of Young's modulus and dynamic mechanical properties of a new high impact resin, ATS (acrylonitrile-styrene copolymer polymerized in the presence of ethylene-propylene-triene terpolymer), on the composition and morphology of the dispersed phase is examined and compared to that of ABS resins (acrylonitrile-styrene copolymer polymerized in presence of polybutadiene). The relationship between modulus and composition is different for the two resins because of the different morphology of the rubbery phases. The experimental results are compared to the predictions of several mathematical models. This analysis is extended to the dynamic moduli E′ and E″, measured over a wide range of temperatures covering the main transition of the rubbery phases.

AbstractThe application of polydicyclopentadiene (polyDCPD) as a high-performance thermosetting resin is often hindered by the simplicity and limitation of the polymer structure, making it unlikely to improve their thermal and dynamic mechanical properties by further optimizing the polymerization conditions. In this study, we developed a copolymer system which consisted of dicyclo-pentadienes and various designed monomers as excellent curing agents. The incorporated monomers bearing different stiffness and rigidity contain two active functional groups at the end of the structures and are capable of reinforcing original polyDCPD. The incorporated monomers notably enhanced the thermal and dynamic mechanical properties of polyDCPD. Besides that, the relationship between the stiffness of the monomer and the thermal and dynamic mechanical properties of polyDCPD was evaluated in detailed. Because of the simplicity and adjustability of copolymerization approach, optimal conditions of the copolymers with best property-reinforcing capability were systemically identified. The optimal materials displayed desired thermal and dynamic mechanical property and markedly outperformed the original polyDCPD.
