  Polyurea resins having excellent mechanical properties and high heat resistance can be prepared by the reaction of an aromatic polyamine component and an aliphatic polyisocyanate component, in which the aromatic polyamine component is a combination of a first aromatic polyamine compound which is typically a polyoxyalkylene-bis(aminobenzoate) compound and a second aromatic polyamine compound selected from various classes of aromatic polyamine compounds different from the first aromatic polyamine compound, in a specified weight proportion. The polyurea resin can be imparted with further improved heat resistance when the aliphatic polyisocyanate component is a combination of an aliphatic diisocyanate compound and a cyclic trimer of an aliphatic polyisocyanate compound in a specified weight proportion.

  通过芳香族多胺组分和脂肪族多异氰酸酯组分的反应，可以制备出具有优异机械性能和高耐热性的聚脲树脂，其中芳香族多胺组分是第一芳香族多胺化合物（通常为聚氧亚烷基双（氨基苯甲酸酯）化合物）和第二芳香族多胺化合物（选自不同于第一芳香族多胺化合物的各类芳香族多胺化合物）按特定重量比例的组合。当脂肪族多异氰酸酯组分是脂肪族二异氰酸酯化合物和脂肪族多异氰酸酯化合物环状三聚体按特定重量比例的组合时，聚脲树脂的耐热性能可进一步提高。

  The present invention relates to a urethane resin obtained by reacting a polymerizable composition containing at least a urethane prepolymer (B2) having an iso(thio)cyanate group at an end of a molecule thereof, which is obtained by reacting a bifunctional active hydrogen-containing compound (C1) having two groups having active hydrogen in a molecule thereof and a bifunctional iso(thio)cyanate group-containing compound (B1) having two iso(thio)cyanate groups in a molecule thereof, a polyrotaxane (A) having a composite molecular structure formed by an axial molecule and a plurality of cyclic molecules clathrating the axial molecule, in which side chains having a group having active hydrogen are introduced into at least a part of the cyclic molecules, and a polyfunctional active hydrogen-containing compound (C2) other than the polyrotaxane (A) and having three or more groups having active hydrogen in a molecule thereof. In accordance with the present invention, it is possible to provide a urethane resin for a sliding member with high abrasion resistance and capable of being suitably used as a polishing pad.

  本发明涉及一种聚氨酯树脂，该聚氨酯树脂是由至少含有在其分子末端具有异(硫)氰酸酯基团的聚氨酯预聚物(B2)的可聚合组合物与在其分子中具有两个活性氢基团的含双官能团活性氢化合物(C1)和在其分子中具有两个异(硫)氰酸酯基团的含双官能团异(硫)氰酸酯基团化合物(B1)反应而得、具有由轴向分子和包覆轴向分子的多个环状分子形成的复合分子结构的聚二氧杂环戊烷（A），其中至少有一部分环状分子中引入了具有活性氢基团的侧链；以及除聚二氧杂环戊烷（A）之外的多官能团含活性氢化合物（C2），其分子中具有三个或更多的活性氢基团。根据本发明，可以提供一种用于滑动部件的聚氨酯树脂，该树脂具有高耐磨性，可适当用作抛光垫。
