Abstract: A release film for pressure-sensitive silicone adhesives which comprises: any of various bases; a primer layer (first layer) disposed on at least one surface of the base, the primer layer having a specific thickness and comprising as a main component an organosilicon compound having a plurality of silanol groups in the molecule; and a release layer (second layer) disposed on the outer surface of the primer layer, the release layer having a specific thickness and comprising as a main component a cured object obtained from a hydrolyzable fluorinated compound. A release coating film having excellent releasing properties can be stably and easily imparted to various bases, and the primer layer and the release layer can be formed even by room-temperature (25° C.) application.

Abstract: Disclosed herein is a shelf-stable, two-part formula for making an antimicrobial biphasic polymer. Some variations provide a two-part formula for fabricating a biphasic polymer, wherein the two-part formula consists essentially of (A) a first liquid volume, wherein the first liquid volume comprises: a structural phase containing a solid structural polymer; a transport phase containing a solid transport polymer; a chain extender; a curing catalyst; a first solvent; and (B) a second liquid volume that is volumetrically isolated from the first liquid volume, wherein the second liquid volume comprises: a crosslinker that is capable of crosslinking the solid structural polymer with the solid transport polymer; and a second solvent. An antimicrobial agent (e.g., quaternary ammoniums salts) may be contained in the first liquid volume or in the second liquid volume. Methods of making and using the antimicrobial biphasic polymer are described.

Abstract: The present invention is directed to a process for preparing light curable energetic polymeric binders. The process for preparing such binder comprises the steps of mixing a pre-polymer such as PGN or GAP having a terminal hydroxyl group with a solvent and adding reactants wherein the reactant has a light curable moiety and a pre-polymer reactive moiety. Catalysts such as carbodiimide and DMAP may be further added to the mixture.

Abstract: Some variations provide a multiphase polymer composition comprising a first polymer material and a second polymer material that are chemically distinct, wherein the first polymer material and the second polymer material are microphase-separated on a microphase-separation length scale from about 0.1 microns to about 500 microns, wherein the multiphase polymer composition comprises first solid functional particles selectively dispersed within the first polymer material, and wherein the first solid functional particles are chemically distinct from the first polymer material and the second polymer material. Some embodiments provide an anti-corrosion composition comprising first corrosion-inhibitor particles or precursors selectively dispersed within the first polymer material, wherein the multiphase polymer composition optionally further comprises second corrosion-inhibitor particles or precursors selectively dispersed within the second polymer material. These multiphase polymer compositions may be used for other applications, such as self-cleaning, self-healing, or flame-retardant coatings. Methods of making and using these multiphase polymer compositions are disclosed.
