Abstract
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 μm; and (b) oxidizing the resin particles in their solid state to produce a wax having a predetermined acid number.
Claims23
A method for producing an oxidized wax comprising:
- a. providing a high molecular weight uniform polyolefin resin feedstock having an average particle size from about 80 mesh to about 30 mesh, and a standard deviation in particle size of not greater than about 125 μm;
- and
- b. oxidizing said high molecular weight polyolefin resin particles in their solid state to produce a wax having a predetermined acid number.
A method for preparing an aqueous emulsification comprising:
- a. providing a high molecular weight polyolefin resin feedstock having an average particle size from about 80 mesh to about 30 mesh and a standard deviation in particle size of less than about 125 μm;
- b. oxidizing said high molecular weight polyolefin resin particles in their solid state to produce a wax having a predetermined acid number;
- and
- c. combining said wax with an aqueous medium to form an emulsion having a Klett value of less than about 175 and a pH of about 4 to about 10.
