AbstractInterpenetrating polymer networks made of dicyclopentadiene and methyl methacrylate or tri(ethylene glycol) dimethacrylate have been successfully prepared by non-interfering frontal polymerization. The role of catalyst and free radical initiator relative amounts, as well as of monomer ratio, has been thoroughly studied. The conditions under which a pure frontal polymerization occurs, and the related values of both front velocity and maximum temperature reached by the reaction, are presented and discussed.

Absorption Theory

Based on the molecule design and energy absorption theory of polymer macromolecule materials, we synthesized a kind of multicomponents interpenetrating polymer network(IPN) which composed of polyurethane(PU), epoxy(EP) and unsaturated polymer resin(UPR). In order to further widen the damping temperature region of polymer materials, we introduced the polydimethylsiloxane (PDMS) into polyurethane(PU). Because of solubility parameter difference between PDMS and PU, we synthesized PDMS modified PU by blocking and grafting PDMS chain into PU main chain firstly. Then, a serious of interpenetrating polymer networks (IPN) which composed of PDMS-PU, EP and UPR were designed and synthesized. The damping performance and microstructure were characterized by using the spectrum of dynamic mechanical thermal analysis (DMTA) and the scanning electron microscope(SEM) respectively. The tested result indicated that the multicomponents IPN which modified by PDMS has wider temperature range and higher damping loss factor, and the PDMS grafting PU/EP/UPR shows good damping performance and microphase compatibility specially.

The One

The main methods (pressing and winding) of the processing of hybrid polymer composites to obtain items were examined. Advantages and disadvantages of the methods were noted. Good combinations of different-module fibers (carbon, glass, boron, organic) in hybrid polymer materials are described, which allow one to prepare materials with high compression strength on the one hand, and to increase fracture energy of samples and impact toughness on the other hand.
