Popis:	Compatible interpenetrating polymer networks systems (IPS) have been obtained by two-stage polymerization of a mixture of diisocyanates (M 1 ) with various different polar monomers (M 2 ) initiated by catalytic systems based on tertiary amines. In the first stage, a polyisocyanate network (P 1 ) is formed and then M 2 is polymerized on a regenerated active centre with the formation of a linear polymer (L 2 ) specially arranged in P 1 . The essential features of the formation of IPS of this type are considered. Some physico-mechanical and thermal characteristics are reported.
