摘要 |
Expandable polymers in particle form for the preparation of foams having high heat distortion resistance contain from 20 to 94.9% by weight of a styrene polymer, from 0.1 to 75% by weight of a polyphenylene ether and from 5 to 20% by weight of a blowing agent mixture of aliphatic or cycloaliphatic hydrocarbons on the one hand and aromatic hydrocarbons, alcohols, ketones, ethers, esters and/or chlorohydrocarbons on the other hand.
