| titleOfInvention | A New Foamed Polyurethane-Polyurea, and a Process for its Production |
| abstract | 1,160,042. Polyurethane-polyurea. UGINE KUHLMANN. 1 March, 1967 [2 March, 1966], No. 9715/67. Heading C3C and C3R. [Also in Division A3] A solid flexible polyurethane-polyurea has a cellular portion and a compact elastomeric skin, the elastomeric skin providing a thick surface layer for the cellular portion and representing 0À1 to 90 volume per cent of the polyurethane-polyurea, there being no transition zone of different density separating the cellular portion and the elastomeric skin. It may be prepared by (A) forming a mixture of a polyisocyanate, a polyether or polyester polyol, an aromatic polyamine, aliphatic polyamine, aminoalcohol, hydrazine or a hydrazide or a mixture thereof, a foaming which is not entirely water, and a catalyst, (B) pouring the resulting mixture into a mould which is at or below a temperature of 20‹ C. and (C) removing the polyurethane-polyurea from the mould after completion of expansion, the components and temperature of the mixture and the temperature of the mould being chosen to give a creaming time of less than 20 seconds and an expansion period of less than 60 seconds. In examples the polyurethane-polyurea is formed from (1 to 3) a prepolymer derived from polypropylene glycol and tolylene diisocyanate, 3,3<SP>1</SP>-dichloro- 4,4<SP>1</SP>-diaminodiphenylmethane, methylene chloride as blowing agent and adipic acid as catalyst and (4) a prepolymer derived from oxypropylated pentaerythritol and tolylene diisocyanate, 3,3<SP>1</SP>-dichloro-4,4<SP>1</SP>-diaminediphenylmethane, p, p<SP>1</SP>-diaminodiphenylmethane, an adduct of propylene oxide and ethylene oxide with ethylene diamine, lead naphthenate as catalyst and trichlorofluoromethane. A portion of the mould may be heated to 60 to 80‹ C. to produce a polyurethane-polyurea, part of which corresponding to the portion of heated mould, is free of the elastomeric skin. |
