| Abstract: | Compatible interpenetrating polymer networks systems (IPS) have been obtained by two-stage polymerization of a mixture of diisocyanates (M1) with various different polar monomers (M2) initiated by catalytic systems based on tertiary amines. In the first stage, a polyisocyanate network (P1) is formed and then M2 is polymerized on a regenerated active centre with the formation of a linear polymer (L2) specially arranged in P1. The essential features of the formation of IPS of this type are considered. Some physico-mechanical and thermal characteristics are reported. |
