Abstract: A N,N'-disubstituted N-(2-hydroxyalkyl) urea is prepared from hexamethylene diisocyanate trimer having a reduced free isocyanate group content and is non-crystalline. A non-crystalline N,N'-disubstituted N-(2-hydroxyalkyl) urea (I) is of formula (1) (1) R = a residue of a trimerised hexamethylene diisocyanate having a reduced free NCO group content; R = an aliphatic or aromatic hydrocarbon having up to 18C atoms, optionally substituted by hydroxyl, cyano or halogen; R = 1-12 alkyl n = 3.0-5.0 on average.

Abstract: Compact or cellular, elastic mouldings, with a closed surface, are prepd. from polyurethane-urea elastomers based on (a) polyisocyanates, (b) higher mol. polyhydroxy or polyamino cpds. with at least 2 reactive H, (c) as chain extender a diaminodiphenylurea of formula (I) opt. (d) catalysts, (e) small amts. of ethylene glycol, (f) further chain extenders and/or cross-linking agents, (g) blowing agents and (h) side and/or additives. Components (a)-(g) are processed as a 1-shot system by high or low pressure reaction injection moulding. In (I) R1-R4 = H or 1-6C alkyl, and the amino gps. are in m-and/or p-position to the urea gp.. (c) (I) is used as a powder with grain size 1-50 (3-10) microns, and may contain a higher mol., multi-ring prod. of formula (Ia), where n = at least 2.
