Title: John Christiansen: Innovator in Polyethylene Terephthalate Resin Compositions
Introduction
John Christiansen is a notable inventor based in Edison, NJ (US). He has made significant contributions to the field of materials science, particularly in the development of advanced resin compositions. With a total of 2 patents, his work has implications for various applications in manufacturing and product design.
Latest Patents
Christiansen's latest patents focus on high gloss polyethylene terephthalate reinforced resin compositions. The first patent describes polyethylene terephthalate resin compositions that include fillers, reinforcing agents, or blends of such fillers and agents, along with alkali metal silicates, carbonates, or bicarbonates, and neopentylglycol dibenzoate. This innovative composition allows for the production of articles with high gloss surfaces and heat deflection temperatures when molded at temperatures below 110°C, even without a precompounding drying stage. The inclusion of neopentylglycol dibenzoate surprisingly reduces the concentration of alkali metal silicates, carbonates, or bicarbonates needed while maintaining the desired high gloss surfaces.
The second patent also addresses high gloss polyethylene terephthalate reinforced resin compositions. This composition includes fillers, reinforcing agents, or blends of such fillers and agents, along with selected alkali metal salts that have anions which are oxides of Group IV of the periodic table, preferably carbonates and bicarbonates. Similar to the first patent, articles molded from these compositions exhibit high gloss surfaces and heat deflection temperatures when molded at temperatures below 110°C, again without requiring a precompounding drying stage.
