Latest Patents

One of Lazear's latest patents is focused on "Hydrophilic monomer treated microporous films and process." This invention addresses the challenge of rendering normally hydrophobic polyolefinic open-celled microporous films relatively permanently hydrophilic. The process improves water flow rates and reduces electrical resistance by chemically fixing a controlled amount of hydrophilic organic hydrocarbon monomer to the surface of the micropores using ionizing radiation. The careful control of the hydrophilic monomer amount prevents pore plugging after radiation treatment.

Another significant patent is for "Pressure sensitive adhesive compositions comprising a mixture of." This invention discloses a pressure-sensitive adhesive composition that boasts improved adhesive strength and tack. The composition consists of three terpolymers, each containing an alkyl acrylate with a carbon chain of four to fourteen atoms, a vinyl ester of a saturated carboxylic acid with one to six carbon atoms, and an ethylenically unsaturated carboxylic acid with three to five carbon atoms. The final terpolymer composition is characterized by a specifically defined number average molecular weight and molecular weight distribution.
