Die Einwirkung von Oxalylchlorid auf N‐Hydroxymethyl‐benzamid (4) führt zu N‐Benzoyl‐1,3‐oxazolidin‐4,5‐dion (8), wenn man den entstehenden Chlorwasserstoff mittels Zugabe von Kalium‐carbonat oder Durchleiten von Stickstoff entfernt. Anderenfalls bildet sich unter Abspaltung von Chlorwasserstoff, Kohlenmonoxid und ‐dioxid N‐Chlormethyl‐benzamid (6). – Chloral‐ oder Bromal‐acylamide 10 und Oxalylchlorid

There is provided a process for producing a styrenic graft copolymer which comprises coplymerizing a styrenic monomer and a styrenic monomer having a hydrocarbon radical with an unsaturated bond in the presence of a catalyst comprising as primary ingredient (A) a transition metal compound and (B) a contact product of an organoaluminum compound and a condensation agent or (C) a compound which produces an ionic complex by reacting with the above-mentioned transition metal compound and subsequently graft polymerizing an ethylenically unsaturated monomer onto the resultant styrenic copolymer.
The above-described styrenic graft copolymer is greatly improved in terms of compatibility, adhesivity, coatability and wettability while preserving heat resistance and chemical resistance thereof, and thus effective as a variety of constructional materials and compatibilizing agents. Furthermore, the composition or multi-layer material comprising the above-mentioned styrenic graft copolymer is widely utilized in a variety of application field including film, sheet, especially stampable sheet, container, packaging material, automobile parts, electrical and electronic parts, etc.
