| abstract | 1,138,205. Polyureas and polyurea-polyurethanes. MERCK & CO. Inc. 22 Nov., 1965 [24 Nov., 1964], No. 49520/65. Heading C3R. [Also in Divisions B2 and C5] A reaction product which at 25 C. will tolerate at least an equal volume of mineral spirits is prepared by reacting a diisocyanate of the formula wherein X is hydrogen or a carboalkoxy group containing at least 4 carbon atoms in the alkyl residue, and when X is carboalkoxy, R is an alkyl radical of at least 4 carbon atoms and when X is hydrogen, R is an alkyl radical of at least 8 carbon atoms; n is 2 or 3; with a compound which is (1) a diamine of the formula R 2 -NH-G-NH 2 where R 2 is an alkyl or a straight chain ethylenically unsaturated hydrocarbon radical of 6 to 20 carbon atoms; G is (CH 2 ) m and m is at least 2 and the sum of carbon atoms in R 2 and G is 14 to 28 or (2) a mixture of (1) and a polyol containing at least three times as many carbon atoms as hydroxy groups, said mineral spirits having a boiling range of 161-197 C. and Kauri-Butanol value of 39. The diisocyanates are the phosgenation products of the relevant esters of ornithine, lysine, 2,5-diamino adipic acid and 2,6-diamino pimelic acid, that exemplified being the octyl ester of lysine diisocyanate. Suitable polyols are hydroxy terminated polyesters which may be derived from " Dimer Acids " by reaction with glycols, polybutylene glycol, long chain glyceryl esters such as glyceryl monostearate and castor oil and suitable diamines are N- substituted trimethylene diamines, the substituents being the hydrocarbon moiety of coconut, soya, oleic and tallow fatty acids. Copolymers may be produced by reacting an NCO group containing product derived from an excess of the above diisocyanates and a polyol with an amino group containing product which has been prepared from excess of the above diamines and one of the above diisocyanates. |
