Abstract

1,168,866. Polycarbamate-dihydropyran aldehyde polycondensates and foams. IMPERIAL CHEMICAL INDUSTRIES Ltd. 30 Jan., 1968 [28 Feb., 1967], No. 9497/67. Headings C3C and C3R. A polymer is obtained by condensing a polycarbamate of molecular weight at least 148 with 2 - formyl - 3: 4 - dihydro - 2H - pyran (acrolein dimer) or a substitution derivative thereof in the presence of a catalyst. The product contains units wherein R and R<SP>1</SP> represent H, halogen atoms or alkyl radicals, linked by polycarbamate residues. Suitable polycarbamates may be derived from polyhydroxy polyethers or polyesters, hydroxyl-containing glycerides or diols by replacing -OH groups by -O.CO.NH 2 groups, e.g. by reaction with COCl 2 followed by NH 3 , or with urea or ethyl carbamate. Suitable hydroxy compounds are reaction products of cyclic oxides with compounds containing 2 or more active hydrogen atoms (lists), polycarboxylic acid/polyol polyesters (lists), castor oil, hydrogenated castor oil, hexadecane diol and dodecane diol. Suitable formyldihydropyrans include acrolein dimer, and the 2- or 5- or 2: 5-C 1-4 alkyl-substituted or 2: 5 dihalo compounds, e.g. methacrolein dimer. Suitable catalysts include p-toluenesulphonic acid and BF 3 etherate (lists), in amount 0À005-5 wt. per cent of the polymer, optionally in solution (list). Blowing agents, e.g. halogenated hydrocarbons (list), and siloxane-oxyalkylene copolymers may be added, if the resin is to be foamed. Pigments, stabilizers, plasticizers and flameproofing agents may be added. The reaction may be conducted in solution or emulsion or by casting, e.g. as a foam. In Examples foams are prepared from acrolein dimer, with CFCl 3 and a siloxane-oxyalkylene block copolymer, and polycarbamates derived from polyoxypropylated sorbitol or hexanetriol (i.p.o. p-toluenesulphonic acid) or from castor oil or polyoxypropylated trimethylolpropane (i.p.o. BF 3 etherate); solids or rubbers are prepared from acrolein dimer, optionally with allyl carbamate, and castor oil or polyoxypropylated trimethylolpropane i.p.o. p-toluenesulphonic acid or BF 3 etherate.
