Abstract: A composition having pH of 5 or less comprises composite particles dispersed in an aqueous continuous liquid phase. Each composite particle comprises a polymer core surrounded by a silicaceous shell. From 3 to 50 percent of silicon atoms in the silicaceous shells are bonded to respective organic groups via a silicon-carbon covalent bond. The weight ratio of the total amount of the silica in the composition to the total amount of the at least one polymer is from 0.1 to 19. The composition is useful for making various articles. A method for making the composition is also disclosed. Silicaceous particles dispersed in an aqueous phase, wherein from 3 to 50 percent of silicon atoms in the silicaceous particles are bonded to organic groups via a silicon-carbon covalent bond are also disclosed.

Abstract: The present invention provides a pressure-sensitive adhesive composition, including: an acrylic copolymer and a crosslinking agent. The acrylic copolymer is a reaction product of a mixture of the following monomers: a first alkyl (meth)acrylate, an alkyl group in the first alkyl (meth)acrylate having at least 6 carbon atoms; a second alkyl (meth)acrylate, an alkyl group in the second alkyl (meth)acrylate having 1 to 5 carbon atoms; and a vinyl carboxylic acid, the weight ratio of the vinyl carboxylic acid to the mixture being 4% to 5%. The crosslinking agent is an organometallic chelating agent. The weight ratio of the organometallic chelating agent to the mixture is 0.05% to 0.25%. The pressure-sensitive adhesive composition does not contain an effective amount of a tackifier. The present invention further provides a pressure-sensitive adhesive solution, a pressure-sensitive adhesive tape, and a method for preparing the same. The pressure-sensitive adhesive of the present invention is a removable pressure-sensitive adhesive, and is applicable in hot weather and cold weather, and the adhesiveness of the pressure-sensitive adhesive does not decrease over time.
