Rigid foams are made by reacting a polyisocyanate with an isocyanate-reactive composition which includes at least one isocyanate-reactive compound, preferably, an amine-initiated polyol and more preferably, an amine-initiated polyether polyol and a second, different polyol in the presence of a blowing agent composition which includes water and a catalyst composition which includes two different blowing catalysts, preferably, pentamethyldiethylenetriamine and bis(2-dimethylamino-ethyl)ether.

Rigid, dimensionally stable polyurethane foams and a process for the production of such foams in which the foam pressure is reduced

A thermoplastic, resinous mixture, useful in the preparation of compatible blends of polyurethane with polyolefins, is disclosed. The mixture contains

Thermoplastic composition containing polyurethane and polypropylene

A thermoplastic copolycarbonate resin having improved low temperature impact strength and a process for the preparation of the resin are disclosed. Accordingly the structure of the copolycarbonate contains

Copolycarbonate having improved low-temperature impact strength
