METHOD FOR PREPARING OXIDIZED POLYOLEFIN WAXES

摘要

A method for producing an oxidized wax comprising (a) providing a uniform high molecular weight polyolefin resin feedstock having an average particle size smaller than about 30 mesh and a standard deviation in particle size of not greater than about 125 mum; and (b) oxidizing the resin particles in their solid state to produce a wax having a predetermined acid number.
