Rubber-modified thermoplastic resin and composition comprising the same |
摘要 |
<p>A rubber-modified thermoplastic resin which 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 x 10<-4> to 50 x 10<-3> and a grafting degree of 5% by weight or more; and a thermoplastic resin composition comprising the above rubber-modified thermoplastic resin and at least one other thermoplastic resin. This thermoplastic resin composition is excellent in gloss, impact resistance and mechanical strength and can well inhibit such an undesirable phenomenon that fish eyes are formed. Moreover, when the rubber-modified thermoplastic resin is modified so that the storage elastic modulus of the acetone-soluble matter thereof becomes 5 x 10<7> to 1 x 10<9> Pa and then used in the above thermoplastic resin composition, the above-mentioned effect is much more improved.</p> |
