Abstract

1408943 Polyester foam products BAYER AG 10 Nov 1972 [13 Nov 1971] 52016/72 Heading C3R In a process for producing moulded foam resin products with solid non-cellular surfaces and a density reducing from the surfaces towards the centre by foaming a reactive mixture of a polyisocyanate and an aromatic polyamine and optionally a polyether or polyester polyol in the presence of a blowing agent in a closed mould the polyisocyanate is a prepolymer obtained from a polyisocyanate and a compound having reactive hydrogen atoms and the polyamine is an amine of the formula or a mixture thereof with amine of formulae where n is 0, 1 or 2; R<SP>1</SP>, R 1 and R 3 or C 1-7 alkyl and R<SP>11</SP>, R 2 and R 4 are H or C 1-7 alkyl. The reactive hydrogen compound in the isocyanate prepolymer may be a polyamine, polyol, polycarboxy compound or polythiol of molecular weight 500 to 500. All the examples use a 2 component procedure wherein component A comprises the diamine together with silicone stabilizer, 1 - methyl - 4 - (N,N - dimethylaminoethyl)piperazine or 1,3,5 - (N,N - dimethyl - aminopropyl) - hexahydrotriazine, and monofluorotrichloromethane and component B the isocyanate prepolymer and sometimes further monofluorotrichloromethane. The polyamines used in components A are condensates of formaldehyde with (Examples 2, 6 and 7) 2,6-diisopropyl aniline, (Examples 1 and 5) a mixture thereof with 2-isopropyl- and 2,6-diethylanilines, (Example 3) 2,6-dimethylaniline and (Example 4) 2-methyl aniline. The isocyanate prepolymers in component B are (Examples 1 to 4) a mixture of prepolymers of (i) hexamethylene - 1,6 - diisocyanate and dipropylene glycol and (ii) tolylene diisocyanate and a mixture of polypropylene glycol 1000 and poly-(propylene-ethylene(glycol 4000; (Example 5) prepolymer (i) above only; (Example 6) tolylene- 2,4-diisocyanate and a mixture of the three glycols of (i) and (ii) above; and (Example 7) tolylene-2,4-diisocyanate and a mixture of di- and tri-propylene glycols and addition compound of propylene oxide to glycerol of M.W. 2600.
