Title:
変性熱可塑性樹脂の製造方法および変性熱可塑性樹脂
Document Type and Number:
Japanese Patent JP3979017
Kind Code:
B2
Abstract:
A process for producing modified thermoplastic resin by subjecting a thermoplastic resin to a modifying reaction in a molten state, comprising performing the modifying reaction using carbon dioxide as the reaction medium, wherein carbon dioxide is used in a proportion of 2 - 200 parts by weight per 100 parts by weight of the thermoplastic resin, whereby the efficiency and the uniformity of the reaction can be increased to a high extent while attaining considerable decrease in the remaining amount of the unreacted components in the resulting modified thermoplastic resin without having recourse to the use of an organic reaction solvent, so that the production can be realized easily at a low cost in an efficient manner.
