Title:
多相シリコーンアクリルハイブリッド粘弾性組成物及びその製造方法
Document Type and Number:
Japanese Patent JP6643344
Kind Code:
B2
Abstract:
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.
