Problems: Thermoplastic resins involve various problems such as enhancement of strength, imparting toughness, improvement of heat resistance and the like. In order to solve there problems, copolymerization with monomers or oligomers, and grafting have been carried out. As a method for solving the problems, graft polymerization with macromonomers was proposed, however, development of modification techniques for achieving more favorable performances, and resins produced thereby have been still desired. Means for Resolution: The present invention relates to a thermoplastic resin prepared by addition polymerization of an addition polymerizable monomer, the thermoplastic resin being modified by copolymerization of said addition polymerizable monomer with a vinyl polymer (I) that has one or more polymerizable carbon-carbon double bond-containing groups at two or more molecular ends each, and has a value of ratio (Mw/Mn) of the weight average molecular weight (Mw) to the number average molecular weight (Mn) being less than 1.8. |
