Abstract: CYCLODODECYLMETHYL CYCLODOECANECARBOXYLATE IS DISCLOSED AS A NOVEL COMPOSITION OF MATTER WHICH MAY BE NITROSATED WITH NITROSYLSULFURIC ACID TO LAURINLACTAM. THE LACTAM IS CONVERTED BY CONVENTIONAL METHODS INTO NYLON 12. NYLON 12 IS BECOMING AN INCREASINGLY IMPORTANT POLYMER COMPOSITION FOR THE MANUFACTURE OF MOLDED ARTICLES, FIBERS AND THE LIKE. THE PRESENT INVENTION RELATES TO A NOVEL ESTER COMPOSITION OF MATTER WHICH MAY BE EMPLOYED IN THE SYNTHESIS OF LAURINLACTAM WHICH IN TURN IS USED IN THE MANFACTURE OF NYLON 12. THE PRESENT INVENTION ALSO RELATES TO A METHOD FOR MANUFACTURING SUCH ESTER COMPOSITIONS.

Abstract: POLYPROPYLENE IS RENDERED FLAME RETARDANT BY THE INCORPORATION OF N,N''-HEXANE-1,6-BIS(5,6-DIBROMONORBORNANE2,3-DICARBOXIMIDE). IF DESIRED, THE FLAME RETARDANCY MAY BE ENHANCED WITH SYNERGISTS, SUCH AS CERTAIN METAL COMPOUNDS (E.G, ANTIMONY TRIOXIDE) AND CERTAIN ORGANIC PHOSPHITES (E.G, DISTERAYL PENTAERYTHRITOL DIPHOSPHITE).
