Ionomeric particulate composition

摘要

An ionomeric particulate composition made by suspension polymerization is provided. The composition comprises at least one vinyl monomer; an acid monomer; a metal oxide; at least two surfactants, one of which is a monomer surfactant; and polyacrylamide. The particulates' size can be controlled by use of the polyacrylainide and various surfactants, and not through the conventional means of homogenization. Particle size in the range of less than 10 micrometers can be made. The ionomeric particulate is made in the absence of a chain transfer agent and thus can have high molecular weight.
