Abstract
Thermosetting resin compositions with low shrinkage are provided, which when molded show low shrinkage rates, good dimensional stability (little cracking or warping), and excellent surface smoothness, mechanical strength, and dispersion stability. The thermosetting resin compositions with low shrinkage in accordance with the present invention comprise: (a) 100 wt. parts by weight thermosetting resins, and (b) 3 to 200 parts by weight polycarbonates containing constituent units derived from aromatic dihydroxy compounds. The polycarbonates preferably have at least 5% (of all the terminal groups) terminal hydroxyl groups derived from aromatic dihydroxy compounds. The polycarbonates also preferably have an intrinsic viscosity of 0.05 to 0.65 dL/g.
