Novel polyphenylene ether-polyamide compositions having improved compatibility, elongation and impact properties as well as improved processability are prepared comprising one or more polyphenylene ethers, one or more polyamides and a property improving silane derivative compound having in the molecule both (a) at least one silicon bonded to a carbon through an oxygen link and (b) at least one ethylenic carbon-carbon double bond or carbon-carbon triple bond and/or functional group selected from the group consisting of an amine group or a mercapto group, with the proviso that the functional group is not directly bonded to a silicon atom. These compositions may further comprise a polymeric impact modifier therefore and/or an inorganic reinforcing additive and/or other polymers including alkenyl aromatic polymers.
新型聚苯醚-聚酰胺组合物具有更好的相容性、伸长率和抗冲击性能以及更佳的加工性能,该组合物由一种或多种聚苯醚制备而成、一种或多种聚酰胺和一种性能改善型
硅烷衍
生物化合物,其分子中同时具有(a) 至少一个通过氧键与碳键结合的
硅和(b) 至少一个
乙烯碳碳双键或碳碳三键和/或选自胺基或巯基的官能团,但官能团不直接与
硅原子结合。因此,这些组合物可进一步包含聚合物抗冲改性剂和/或无机增强添加剂和/或其他聚合物,包括烯基芳香族聚合物。
