IMPACT-RESISTANT RESINS AND THEIR PREPARATION |
摘要 |
What are disclosed are a continuous emulsion polymerization method for making an aqueous dispersion of an impact resistant resin, adaptable to use as a component of impact resistant polymethacrylate forming masses, by first emulsion polymerizing a first monomer component onto core particles of a seed latex until a degree of polymerization of said monomers from 80 to 95 percent is attained, whereby an intermediate product comprising said core particles covered with a rubbery polymer phase is obtained, and then emulsion polymerizing a second monomer component onto the particles of said intermediate product to form a shell of harder polymer on the particles of said intermediate product, and impact resistant resin products made by this method. |
