Spherical-shaped particles from ionomer resins and ethylene/carboxylic acid copolymer resins

摘要

Spherical-shaped particles having an average diameter of 10 to 100 microns and the surface thereof is covered with hemispherical-shaped bumps about 0.1 micron in diameter, the particles being a copolymer of alpha-olefins and alpha, beta-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms, the copolymer having up to 90% of the carboxylic acid groups ionized by neutralization with metal ions. The particles form a free-flowing powder useful in preparing clear, protective, shatter-resistant coatings for glass, and protective coatings for metals and other material.
