Abstract
Rubber articles are coated with a powder-free copolymer coating to provide improved mold release characteristics, improved donning characteristics, and improved tactile feel. The copolymer is formed by the polymerization of a at least one copolymerizable silicone oligomer, at least one alkyl acrylate, and at least one hard monomer. The hard monomer, when homopolymerized, has a glass transition temperature of at least 0.degree. C. The copolymers are preferably formed by a sequential polymerization process.
