Abstract:
1. A crosslinkable polyurea prepolymer, which is a reaction product of an amine- or isocyanate-capped polyurea and a multifunctional compound having at least one ethylenically unsaturated group and a function group coreactive with the capped amine or isocyanate groups of the amine- or isocyanate-capped polyurea, wherein the amine- or isocyanate-capped polyurea is a copolymerization product of a mixture comprising the components of: (a) at least one aminoalkyl polyalkylene glycol of formula (1) (b) optionally at least one organic di- or poly-amine, wherein the organic diamine is a linear or branched C (c) optionally at least one diisocyanate selected from the group consisting of a linear C (d) at least one polyisocyanate having at least three isocyanate groups, wherein the polyisocyanate is selected from the group consisting of a linear or branched C
