Patent number: 5545830Abstract: Pyrene based fluorescent organopolysiloxanes which bear two or more reactive silicon-bonded sites are useful as durable markers and indicators of the degree of cure in curable silicone compositions. Having more than one reactive site the compounds participate in the curing reaction of the curable composition and thus do not adversely affect its curing behavior. The resulting fluorescent curable compositions are particularly useful in the preparation of adhesive-release coatings.Type: GrantFiled: December 30, 1994Date of Patent: August 13, 1996Assignee: Dow Corning CorporationInventors: Maris J.

Patent number: 5169904Abstract: A method for altering a macroporous cross-linked hydrophobic copolymeric lattice produced by precipitation polymerization in a solvent of at least one monounsaturated ester monomer and at least one polyunsaturated ester monomer soluble therein, in order to render the hydrophobic copolymeric lattice hydrophilic. The method involves saponifying the hydrophobic copolymeric lattice by reacting the surface of the hydrophobic copolymeric lattice with an aqueous alkali. The surface can also be rendered hydrophilic by polymerizing an acrylate monomer onto the lattice in order to form a surface containing carboxylic acid sites. The carboxylic acid sites formed on the surface of the lattice are converted to carboxylate anions.Type: GrantFiled: August 6, 1990Date of Patent: December 8, 1992Assignee: Dow Corning CorporationInventors: Maris J.
