Latest Patents

Wojtyna's latest patents include innovative methods and compositions for producing phenolic foams. One of his key inventions is the development of aqueous phenol formaldehyde resoles specifically designed for manufacturing phenolic foam insulation. These resoles are characterized by their molar ratios of formaldehyde to phenol, which range from about 1.7:1 to 2.3:1, with a preferred range of 1.75:1 to 2.25:1. The resoles exhibit a weight average molecular weight greater than 800, ideally between 950 and 1500, and a number average molecular weight exceeding 350, preferably from about 400 to 600. This invention enables the production of phenolic foams with low thermal conductivity, making them particularly effective as insulation materials.

Another significant patent involves a method for preparing phenolic foams that feature cell walls free of perforations. This method utilizes specific anhydrous aryl sulfonic acids as foaming and curing catalysts, which enhance the compatibility of the phenolic resole with water. The preferred catalysts include a combination of toluene sulfonic acid and xylene sulfonic acid, resulting in high-quality phenolic foams.
