Embodiment

[0071] (Manufacture of Polymer 1)

[0072] The oil jacket of a pressurized stirred tank reactor (capacity: 1 liter) equipped with an oil jacket was heated up to 200°C. On the other hand, 69 parts by mass of styrene (hereinafter referred to as St.), 30 parts by mass of glycidyl (glycidyl) methacrylate (methacrylate) (hereinafter referred to as GMA.), 1 part by mass of methacrylic acid Methyl methacrylate (hereinafter abbreviated as MMA.), 15 parts by mass of xylene 15 parts by mass, and 0.5 part by mass of ditertiarybutyl peroxide (ditertiarybutyl peroxide) (hereinafter abbreviated as DTBP) as a polymerization initiator .) After the monomer mixture is prepared, add it to the raw material tank. Then, the monomer mixed liquid was continuously supplied from the raw material tank to the reactor, and the reaction liquid was continuously recovered from the outlet of the reactor so that the mass of the liquid in the reactor remained constant at about 580 g. The feed rate of the mono...

Abstract

Disclosed is a thermoplastic resin composition containing a thermoplastic resin (A) having a functional group reactive with epoxy groups, a polymer (B) having an epoxy group and a catalyst (C) for accelerating reactions of the functional group reactive with epoxy groups and the epoxy group. The content of the polymer (B) is set at 0.1-5 parts by mass per 100 parts by mass of the thermoplastic resin (A), while the content of the catalyst (C) is set at from 1.0 10<-6> to 50 10<-6> parts by mass per 100 parts by mass of the thermoplastic resin (A). Also disclosed is a molded article obtained by molding, for example extrusion molding the thermoplastic resin composition.

Description

technical field [0001] The present invention relates to a thermoplastic resin composition mainly composed of a condensation polymer such as polyester resin and its molded article. More specifically, the present invention relates to a thermoplastic resin composition capable of providing a molded article exhibiting excellent dimensional stability objects and their moldings. Background technique [0002] Condensation polymers represented by polyester resins are widely used in many fields such as bottles, sheets, and films because of their excellent mechanical strength. In particular, polyester resins are widely used as food packaging materials such as bottles and blister packages because of their excellent transparency and hygienic properties. In recent years, out of the consideration of reducing the environmental burden, the activities of recycling and reusing waste resins are very active, especially the recycling and recycling of polyethylene terephthalate (hereinafter refer...
