摘要： Polymer-containing polyether polyamines containing terminal aromatically-bound amino groups are produced by in situ polymerization of a polyether polyamine with an olefinically unsaturated monomer. The polyether polyamine starting material must have terminal aromatic amino groups, a molecular weight of from 800 to 10,000 and an aromatic amino group content of from 0.3 to 16 wt. %. Suitable olefinically unsaturated monomers include .alpha.,.beta.-unsaturated nitriles, aromatic vinyl compounds, .alpha.,.beta.-unsaturated carboxylic acids and esters thereof, vinyl esters, vinyl halides, vinylidene halides, .alpha.,.beta.-unsaturated carboxylic acid amides and aminoalkyl esters of unsaturated carboxylic acids. Acrylonitrile/styrene mixtures are preferred monomers. The starting materials are employed in quantities such that the product modified polyether polyamine contains from 1 to 60 wt. % polymer or graft-polymer. The product polyamines are particularly useful in the production of polyurethanes.

摘要： A deformable and durable polyurethane foam molding is made from the reaction product of a polyether polyol component and a polyisocyanate component. The polyether polyol component is a polyether having at least two hydroxyl groups, a molecular weight of from 400 to 10,000 and at least 10 wt. % hydroxyl groups which are primary hydroxyl groups. The polyisocyanate component is a mixture of from 60-90 wt. % 4,4'-diphenyl methane diisocyanate and from 3-30 wt. % 2,4'-diphenyl methane diisocyanate. Such reaction mixture is prepared in each of at least two mixing heads. The index of reaction mixture is different from that in the other mixing head. The mixture is then introduced into associated zones of a mold cavity where the mixture is allowed to foam. The molding is subsequently removed from the mold cavity. These polyurethane foam moldings are particularly useful in making seat cushions.
