| 摘要 |
Novel thermosetting resin powders which can be molded to form products characterized in tensile measurement, by high elongation-to-break, high tensile strength and modulus and a high glass transition temperature are prepared from a mixture of (a) a prepolymer formed by reacting (1) hydroxy ester of acrylic or methacrylic acid and a C2 - C3 diol with (2) methyl methacrylate and (b) a blocked di- or triisocyanate wherein the isocyanate groups are directly attached to an aromatic ring and deblock at temperatures in the range of about 120 DEG to 160 DEG C. |
