Abstract:
Suggested is a urea urethane with improved rheological properties, obtainable or obtained according to a process encompassing or consisting of the following steps: (a) providing a monohydroxyl compound;(b) providing a diisocyanate compound; (c) reacting said monohydroxyl compound and said diisocyanate compound to form a pre-polymer; (d) reacting said pre-polymer with a diamine compound in the presence of a lithium salt, wherein said monohydroxyl compound and said diisocyanate compound are reacted in a molar ratio of 1:1.1 to 1:1.45.

Claim (Index 4):
A process for obtaining an urea urethane, comprising the following steps:\n (a) providing a monohydroxyl compound of formula (I)\n R\u2014OH\u2003\u2003(I) \n in which R is n-alkyl or isoalkyl containing 4 to 22 carbon atoms, cycloalkyl containing 6 to 12 carbon atoms, aralkyl containing 7 to 12 carbon atoms or a radical of the formula CmH2m+1(O-CnH2n)x- or CmH2m+1(OOC-CvH2v)x-, and m stands for an integer of from 1 to 22, n stands for an integer of 2 to 4, x for an integer of 1 to 15 and v means 4 or 5; (b) providing a diisocyanate compound of formula (II)\n OCN-[A]-NCO\u2003\u2003(II) \n in which A stands for a linear or branched alkylene radical having 2 to 10 carbon atoms or a toluylene radical; (c) reacting said monohydroxyl compound and said diisocyanate compound to form a pre-polymer; (d) reacting said pre-polymer with a diamine compound, said diamine compound being selected from the group consisting of\n (d1) compound (III)\n H2N-[B]-NH2\u2003\u2003(III) \n where B stands for a linear or branched alkylene group having 2 to 12 carbon atoms, \n \n (d2) compound (IV) \n and\n (d3) compound (V) \n in which R\u2032\u2033 stands for hydrogen or a methyl group and mixtures thereof, in the presence of a lithium salt, wherein said monohydroxyl compound and said diisocyanate compound are reacted in a molar ratio of 1:1.1 to 1:1.45.
