  There is provided an oligomeric polyol composition having (a) an oligomeric network containing residues of at least one polyhydroxylated aromatic compound and residues of at least one polyol having at least three hydroxyl groups; and (b) a plurality of peripheral groups having one or more pendant hydroxyl groups bound to the oligomeric network by a plurality of linking units. The residues of the polyol may optionally contain one or more oxygen ether groups, one or more amino ether groups, or both of one or more oxygen ether groups and one or more amino ether groups. Reaction of the oligomeric polyols with isocyanate monomers affords a new class of polyurethanes having superior heat and water resistance. The new polyurethanes exhibit lower peak exotherms, typically less than 250° F. during in-mold polymerization. Articles prepared from polyurethanes incorporating such oligomeric polyol compositions exhibit flexural strengths and moduli in excess of 10,000 psi and 400,000 psi respectively, and outstanding green strength.

  本发明提供了一种低聚多元醇组合物，该组合物具有：(a) 低聚网络，其中包含至少一种多羟基芳香族化合物的残留物和至少一种具有至少三个羟基的多元醇的残留物；以及(b) 多个外围基团，这些外围基团具有一个或多个通过多个连接单元与低聚网络结合的垂羟基。多元醇的残基可选择含有一个或多个氧醚基团、一个或多个氨基醚基团，或同时含有一个或多个氧醚基团和一个或多个氨基醚基团。低聚多元醇与异氰酸酯单体反应可产生一类新型聚氨酯，具有优异的耐热性和耐水性。这种新型聚氨酯的放热峰值较低，模内聚合时通常低于 250°F。用含有此类低聚多元醇组合物的聚氨酯制备的物品，其抗弯强度和模量分别超过 10,000 psi 和 400,000 psi，并且具有出色的绿色强度。
