摘要:
An article that is capable of accepting and anchoring printed indicia and yet, maintains good release properties. The article of the present invention is coated with a release agent on a substrate such as paper. Release coatings receptive to toner particles emitted by electrophotoconductive devices comprise a polymer having at least one vinyl polymeric segment having a T.sub.g between -10.degree. C. and 65.degree. C. and at least one siloxane polymeric segment.

摘要:
A method of preparing vinyl-silicone copolymers which involves the use of a mercapto-functional silicone compound as a macromolecular chain transfer agent. Release coatings and low adhesion backsizes comprising the vinyl-silicone copolymers.
摘要:
Iniferter prepared release coating compositions comprising vinyl-siloxane block copolymer and blends thereof with other polymeric materials on sheet materials and the backside of adhesive tapes are provided. Controlled and predictable release is obtained through variation of the molecular weight and weight percent of the siloxane block as well as the molecular weight and composition of the vinyl block or blocks.

摘要:
A vinylic copolymer comprising repeat units of A, B and C These copolymers have an acid content of 0.015 to 0.50 milliequivalents per gram of copolymer. Compositions that provide these copolymers in easily handled forms, and cosmetic compositions comprising the copolymer are also provided.
摘要:
Blended release materials including a blend of a fluoro-functional silicone release polymer and a fluoropolymer are described. Exemplary fluoropolymers include fluoroolefin-based polymers and linear fluoropolymers including linear fluoroacryaltes. Articles including such release materials such as release liners, and adhesive articles, including silicone adhesive articles, are also described.
