Abstract:
A process for preparing a polymer comprising reacting by high-pressure impingement mixing from about 0.8 to about 1.5 equivalents of a polysocyanate reactant or mixture of polyisocyanate reactants with one equivalent of one or more compounds having isocyanate-reactive hydrogens selected from the group consisting of 1) at least one first polyamine, 2) blends of at least one first polyamine with polyols, 3) blends of at least one said first polyamine with at least one second polyamine, and 4) blends of at least one said first polyamine with at least one polyol and at least one second polyamine, said first polyamine having a structure I-III or V, where R1 and R2 are independently selected from the group consisting of alkyl groups with from 1 up to 20 carbon atoms, R3 and R4 are independently selected from the group consisting of hydrogen and alkyl groups with from 1 up to 10 carbon atoms, R5 and R6 are independently selected from the group consisting of alkyl groups with from 4 up to 20 carbon atoms, and said second polyamine having a structure different from said first polyamine.
