- 摘要：In this review our progress on high heat-resistant silicone rubbers was expounded. The effect on improving the thermal stability of silicone rubbers by introducing Si-N bond into polysiloxane main-chain、using Si-N compounds as additives and using silazane as crosslinking agent was discussed. The mechanism was proposed that the thermal stability of silicone rubbers was improved by removing silanol and water which could lead to main-chain degradation. High heat-resistant polysiloxane elastomers were synthesized by living polymerization.关键词：High heat-resistant;Silicone Rubber;Silazane additive;Anionic polymerization

发布时间：2022-09-18 - 摘要：One of the most important breakthroughs in cationic polymerization in1980s is perhaps the discovery of living cationic polymerization. By now, the scope of living cationic polymerization in terms of initiating systems, monomers and synthetic applications has rapidlly been expanded. In this review, we focus on the progress in synthesis of new block polymers and multiblock polymers by living cationic polymerization.关键词：Living cationic polymerization;Block copolymers

发布时间：2022-09-18 - 摘要：In this paper, the relationship of molecular design and thermal properties of liquid crystalline ionomer was summarized. Usually, the existence of ionic groups in the terminal of main-chain liquid crystalline ionomers almost did not influence the Tg and Tm of the polymers. Tg and Tm decreased with increasing ionic concentration in the main-chain liquid crystalline ionomers. The influence of ions in the side-chain liquid crystalline ionomers depended on the flexibility of main chain and the ionic position in the polymer chain et al. Generally, The Ti decreased with increasing ionic concentration in the chain for both main-chain and side-chain liquid crystalline ionomers.关键词：Liquid crystalline ionomer;Molecular design;Thermal property
