Abstract:
A grafted rubber-containing styrenic resin comprising a matrix comprising a styrenic resin and a rubber component dispersed therein in particle form, wherein the graft ratio of a styrenic monomer relative to the rubber component is not less than 1, and the mean particle size of the dispersed rubber component is 0.1 to 3 .mu.m, satisfying the following equation (1):Mn=aT+b (1)wherein Mn represents the number average molecular weight of the matrix resin, T represents the conversion of the styrenic monomer to the matrix resin, a is a constant greater than 0, and b is a constant greater than or equal to 0, wherein the equation (1) means that the relationship between T and Mn can be approximated by a linear equation.
