<p>A polybutylene terephthalate composition comprises polybutylene terephthalate, polyacrylate and a silane coupling agent and is improved in impact resistance and elongation. Preferably, the composition contains 75 to 99.8 wt.% of the polybutylene terephthalate, 0.1 to 20 wt.% of the polyacrylate and 0.1 to 5 wt.% of the silane coupling agent. The polyacrylate may have a core-shell structure including a rubber-like inner core portion and a thermoplastic rigid outer shell portion. The silane coupling agent may have the formula: Y-R-SiX3 (wherein X is hydrolyzable group such as chlorine, alkoxy, etc., Y is an organic functional part such as glycidyl, vinyl, methacryloxy, epoxycyclohexyl, amino and mercapto and R is a chemical bond or a lower alkylene).</p> |
