摘要

研究了添加四官能团双层硅倍半氧烷（DDSQ-ether-4OH）对聚乳酸和环氧化天然橡胶（PLA/ENR）硫化胶的相容性、热性能和机械性能的影响。此外，还测定了聚乳酸/ENR 硫化物的表观交联密度和热稳定性。傅立叶变换红外光谱分析证实了 DDSQ-ether-4OH 的相容作用以及聚乳酸-ENR 共聚物的形成。ENR 含量和 DDSQ-ether-4OH 添加量对所获硫化胶的热性能和机械性能有很大影响。

Thermal and mechanical properties of PLA/ENR thermoplastic vulcanizates compatibilized with tetrafunctional double-decker silsesquioxanes

The influence of the addition of tetrafunctional double-decker silsesquioxanes (DDSQ-ether-4OH) on the compatibility, thermal and mechanical properties of polylactide and epoxidized natural rubber (PLA/ENR) vulcanizates was investigated. The apparent cross-linking density and thermal stability of PLA/ENR vulcanizates were also determined. The FTIR analysis confirmed the compatibilizing effect of DDSQ-ether-4OH and the formation of the PLA-g-ENR copolymer. A strong effect of ENR content and DDSQ-ether-4OH addition on the thermal and mechanical properties of the obtained vulcanizates was demonstrated.
