Abstract: The invention relates to a process for the preparation of high-molecular-weight polyphenylene ethers from monohydric phenols by conventional polycondensation in which the polymers obtained are reacted with ss-lactones of the formula (I) in which R , R , R and R may be identical or different and are hydrogen atoms or alkyl, cycloalkyl, aryl, carboxyl, carboxyalkyl, nitrile or substituted alkyl groups, and/or are reacted with polymeric propiolactones. Particularly suitable lactones are propiolactone, ss,ss-dimethylpropiolactone, alpha , alpha -diphenylpropiolactone or polymeric propiolactone.

Abstract: Thermoplastic moulding cpds. contain a mixt. of (A) 97 - 40 p.b.w. of a styrene polymerisate contg. at least 50 wt. % polymerised styrene and which may be rubber-modified to render it impact-resistant, and (B) 3 - 60 p.b.w. of a copolymer of 98 - 50 wt.% styrene and 2 - 50 wt.% of an acrylate with 1 - 20 C-atoms in the alcohol residue. Compsns. have good flow characteristics in processing conditions without "sweatingout" of any lubricant present. Mouldings combine good mech. props. with satisfactory heat-deformation strength.
