MULTI-PHASE SILICONE ACRYLIC HYBRID VISCO-ELASTIC COMPOSITIONS AND METHODS OF MAKING SAME

A multi-phase silicone acrylic hybrid visco-elastic composition prepared by polymerizing an ethylenically unsaturated monomer and a silicon-containing pressure sensitive adhesive composition comprising acrylate or methacrylate functionality in a first solvent in the presence of an initiator, removing the first solvent, and adding a second solvent to form the multi-phase silicone acrylic hybrid visco-elastic composition. Alternatively, a multi-phase silicone acrylic hybrid visco-elastic composition prepared by polymerizing an ethylenically unsaturated monomer and a silicon-containing pressure sensitive adhesive composition comprising acrylate or methacrylate functionality in a first solvent in the presence of an initiator, adding a processing solvent having a higher boiling point than the first solvent, applying heat to selectively remove a majority of the first solvent, removing the processing solvent, and adding a second solvent to form the multi-phase silicone acrylic hybrid visco-elastic composition. The phase arrangement of the multi-phase silicone acrylic hybrid visco-elastic compositions is selectively controlled by selection of the second solvent.

SOLID-STATE METHOD FOR TREATING POLYAMIDE AND POLYESTER ARTICLES
20230235132 · 2023-07-27 ·

Solid-state branching and/or crosslinking of aliphatic polyamide or polyester articles is achieved using a topical approach. A surface of the article is coated with a composition that includes a polyene and a free radical initiator. The article and applied coating are then heated to induce branching and/or crosslinking in the polyamide or polyester. This is performed below the crystalline melting temperature of the polyamide or polyester, or in the case of a fabric, below the melting temperature of the fibers in the fabric. Fabrics treated in this manner exhibit reduced or even no dripping in vertical flame tests.
