WERKWIJZE TER BEREIDING VAN MATERIALEN OP BASIS VAN POLY(ALKYLEENTEREFTALAAT), ALSMEDE ONDER TOEPASSING DAARVAN VERVAARDIGDE VOORWERPEN.

摘要

Compositions comprising a blend of poly(alkylene terephthalates) and an impact modifier which is a multi-phase composite interpolymer comprising a crosslinked acrylic first stage which also contains graftlinking monomer and a final rigid thermoplastic phase. Also claimed is the process for improving the impact strength of poly(alkylene terephthalates) comprising blending therewith the multi-phase composite interpolymer modifier defined above.
