ゴムラテックス及びこれの製造方法
Document Type and Number:
Japanese Patent JP2006524718
Kind Code:
A
Abstract:
Provided are a rubber latex used as a substrate for an impact modifier, a preparation method thereof, and an impact modifier prepared using the rubber latex. The rubber latex includes a rubber monomer as a main component and has a decreasing gel content from a core to a shell(s). The preparation method includes polymerizing a core followed by polymerization of a shell(s) has a lower gel content that the core. The impact modifier is prepared by common graft polymerization using the rubber latex as a substrate. The rubber latex has a high gel content core and a low gel content shell (s), and thus, is free from problems involved in low or high gel content rubber particles. The rubber latex can be used as a substrate for a high efficiency impact modifier with high rubber content and enhanced impact strength and processability.
