IMPACT MODIFIED COMPOSITIONS OF COMPATIBILIZED POLYPHENYLENE ETHER-POLYAMIDE RESIN BLENDS

摘要

The invention relates to thermoplastic compositions comprising a compatibilized polyphenylene ether-polyamide resin blend which is modified with an impact modifier containing at least moieties that are reactive with the polyamide resin. The preferred impact modifier is an alkylene-alkyl (meth)acrylate copolymer comprising at least two moieties selected from the group consisting of carboxylic acid, anhydride, epoxy, oxazoline, and orthoester. The compositions of the invention exhibit enhanced physical properties, especially energy at break and deformation when measured at low temperature.
