Introduction

Patrick William Houlihan is an accomplished inventor based in Greenwich, Australia. He has made significant contributions to the field of polymer chemistry, particularly in the development of innovative coating compositions. With a total of five patents to his name, Houlihan's work has had a notable impact on the industry.

Latest Patents

One of his latest patents is for a stain-resistant water-borne coating composition. This invention describes aqueous coating compositions where the binder includes an anionically stabilized polymeric dispersion. The monomers used to prepare the dispersion include acrylic acid and methacrylic acid as a carboxylic monomer, along with styrene, alpha methyl styrene, or vinyl toluene as a hydrophobic high Tg aromatic monomer, and an alkyl acrylate ester as a low Tg monomer. The relative weight proportions of these monomers must satisfy a specific formula. Paints formulated with these binders exhibit an excellent balance of stain resistance, tint strength, and viscosity stability.

Another significant patent involves the preparation of an aqueous dispersion of water-insoluble polymer particles. This process includes preparing an aqueous dispersion of water-insoluble particles of a heteropolymer, which incorporates monomeric units of a reactive amphiphile and a hydrophilic monomer. The polymerization is conducted in the presence of a stabilizing agent and at a temperature above the cloud point of the amphiphile. Cooling the dispersion below the cloud point increases its viscosity, leading to innovative applications in various industries.
