Abstract

1,205,330. Trioxan polymerization. BADISCHE ANILIN- & SODA-FABRIK A.G. 15 Feb., 1968 [16 Feb., 1967], No. 7429/68. Heading C3P. Homo- and co-polymers containing oxymethylene groups are obtained by polymerizing trioxan in the presence of a cationic catalyst, at 60‹ to 120‹ C. in bulk, and in a container comprising a polymer containing recurring groupings in the molecule, which polymer is a stabilizer for the oxymethylene polymer. Suitable polymers include polyamides, polyurethanes, polyureas, and polymers of ethylenically unsaturated monomers such as vinyl pyrrolidone, acrylamide, methacrylamide and N- vinylurethanes and ureas. The examples relate to the copolymerization of trioxan and dioxolan in the presence of BF 3 .(C 4 H 9 ) 2 O, and in one example, butylal, in containers made from nylon-6, a co-polycondensate of caprolactam, adipic acid and hexa-methylene diamine, a copolymer of methyl methacrylate, n-butyl acrylate, and vinyl pyrrolidone and a copolymer of n-butoxymethylmethacrylamide and styrene.
