    Abstract: 1276263 Synthetic resin compositions FARBENFABRIKEN BAYER AG 26 March 1970 [27 March 1969] 14668/70 Headings C3B C3C C3P and C3R Synthetic resin compositions contain as flameproofing agent 5-70% of a copolymer of (a) 2- 30% ethylene or propylene, or mixture of one of these with α-butylene or isobutylene, (b) 98- 20% of a halogen-containing α-olefin, (c) 0- 40% of an OH-containing monomer and (d) 0- 50% of a halogen-containing telogen, the copolymer having a halogen content of 40-80% and a molecular weight of 300-3000. Copolymers, which are oily or greasy, prepared are ethylene/vinylidene chloride, ethylene/vinyl chloride also with hydroxymethyl norbornene, methyl vinyl carbinol, alkyl hydroxypropanol, hydroxypropyl methacrylate, carbon tetrachloride or carbon tetrabromide propylene/vinyl chloride/carbon tetrachloride and ethylene/vinyl bromide/bromoform. In examples they are added to (1) low-pressure polyethylene, (2) vinyl chloride/ethylene copolymer,(3) polyvinyl chloride, (4) polystyrene with antimony trioxide, (5) polyester from butylene glycol, maleic anhydride and phthalic anhydride with styrene and antimony oxide hardened with benzoyl peroxide, (6) diglycidyl ether of bisphenol A hardened with methylhexahydrophthalic anhydride and dimethylbenzylamine, (7) diglycidyl ester of hexahydrophthalic acid with the same hardeners as (6), (8) a styrene suspension, polymerization in the presence of polystyrene, the product being swollen in pentane and expanded in a mould with steam, (11) diphenylmethane diisocyanate, which is then converted into a polyurethane foam with sucrose polyether, N,N-di-#-hydroxyethylamino methyl phosphonic acid diethyl ester, trichlorofluoromethane silicone stabilizer and N- methyl - N - ethyl - dimethylamino piperazine (12)-(17) similar polyurethane foams.

    Abstract: A process is provided for the production of synthetic polyurethane plastics, particularly foam plastics, containing biuret groups by reacting polyisocyanates, polyhydroxyl and/or polycarboxyl compounds, flame inhibitors and, if desired, blowing agents, emulsifiers, activators and other additives which is characterized by using as the polyisocyanate solutions in monomeric polyisocyanates of from about 1 per cent to 85 per cent of polyisocyanates containing biuret groups and having the formula: O PARALLEL OCN-R-N-C-N-R-NCO ¦¦ O=C(CO-N)nH ¦¦ R-NCO H--N-CO)n-N ¦¦ R-NCOR ¦ NCO in which R is an aromatic, araliphatic or cycloaliphatic radical which may, if desired, be substituted and N IS AN INTEGER FROM 0 TO 5, WHEREIN THE PROPORTION OF BIURET-POLYISOCYANATES HAVING MORE THAN THREE ISOCYANATE GROUPS IS AT LEAST 20 PER CENT BY WEIGHT BASED ON THE TOTAL QUANTITY OF BIURET-POLYISOCYANATES, AND THE SOLUTIONS CONTAIN FROM ABOUT 0.03 PER CENT TO ABOUT 5 PER CENT BY WEIGHT OF CHEMICALLY COMBINED EMULSIFIERS.
