Estimating the term…
A rubber-modified thermoplastic resin is obtained by polymerizing (b) an aromatic vinyl compound and (c) a vinyl cyanide compound in the presence of (a) a rubbery polymer, and in which the content of the component (a) is 50 to 85% by weight, the content of the component (b) is 5 to 48% by weight and the content of the component (c) is 2 to 45% by weight, and which resin has a Q value of 30.times.10.sup.-4 to 50.times.10.sup.-3 and a grafting degree of 5% by weight or more. A thermoplastic resin composition comprising the above rubber-modified thermoplastic resin and at least one other thermoplastic resin is prepared.
