CONTINUOUS PRODUCTION PROCESS OF ABS RESIN AND ABS RESIN

摘要

The present invention provides a styrene-based monomer and acrylonitrile step monomer, or monomers thereof in the presence of a rubbery polymer by continuous block polymerization, continuous solution polymerization, or continuous block polymerization and continuous solution polymerization. Polymerization using a monomer component comprising a vinyl monomer copolymerizable with at least one of the monomers, wherein the copolymer of the monomer component comprises a continuous phase and the rubber polymer particles form a dispersed phase. Way.;In the production method of the present invention, a monomer component is formed by using a first flow stage forming step and a complete mixing tank in which polymerization is performed using a plug flow type reaction tank or a batch polymerization tank to form particles of a rubbery polymer. And a step including at least two substeps of the second-sized particle size adjusting part step of increasing the amount of conversion to the polymer of the polymer from the particle forming part step and reducing the particles of the rubbery polymer produced in the particle forming part step.;According to the method of the present invention, it is possible to obtain an ABS resin having excellent impact resistance, good weld strength of a molded article, and significantly improved gloss difference due to the site of the molded article.
