摘要： High impact resistant compositions comprise:

(a) 25-95% by weight of aromatic polyester;
(b) 1 to 50% by weight of aromatic polycarbonate:
(c) the balance to make 100% of core/shell polymer comprising a first elastomeric phase comprising 75 to 99.8% by weight of (C 1 -C 6 )-alkyl acrylate units, 0.1 to 5% cross-linking monomer units, 0.1 to 5% graft-linking monomer units, and final rigid thermoplastic phase, the weight ratio of first to final stages being 25 to 95: 75 to 5 based on a total of 100 parts. The polyester usually used is poly(ethylenetereph- thalate) and the compositions are very suitable for making injection moulded articles and/or glass fibre reinforced articles.

摘要： The content of residual volatile amines in polymers containing at least about 30 weight percent of glutarimide units having the structure

wherein R 1 and R 2 are separately H or CH 3 , and R 3 is H or C 1 - C 4 lower alkyl, canbe reduced to below 50 ppm by subjecting the molten polymer to a temperature of from about 250 to about 300 ° C in an extruder equipped with a means for devolatilization and applying a vacuum of at least about 600 mm. mercury. The polyglutarimides subjected to this process are especially useful in blends with poly(vinyl chloride).
