<p><P>PROBLEM TO BE SOLVED: To provide a shape-memorizing polymer composition having an extended pot life, a fiber-reinforced plastic exhibiting excellent inflatability, and its manufacturing method. <P>SOLUTION: The shape-memorizing polymer composition comprises a bifunctional, a trifunctional, or a bifunctional and trifunctional isocyanate and a polyol having an average molecular weight of 100-550 in a molar ratio of isocyanate:polyol of (0.9-1.1):1.0 in terms of the functional groups. The fiber-reinforced plastic comprises the shape-memorizing polymer composition and a fiber material. The fiber-reinforced plastic is manufactured by impregnating the shape-memorizing polymer composition as the matrix resin with the fiber material and curing the composition. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
