Abstract: Disclosed are mixtures of two or more polymers of which at least one is cross-linked. Interpenetrating polymer networks are on hand. The polymers mix below a certain temperature and demix above this temperature (LCST behavior). Below the demixing temperature, such interpenetrating polymer networks are optically clear, above the demixing temperature they are milky, turbid and have reduced light transmission due to the light scattering of the phaseseparated system' if the refractive indices of the components do not coincide. The demixing process is fully reversible below the demixing temperature.

Abstract: This invention relates to a novel pressure sensitive adhesive formed of a liquid and solid rubber which is substantially resin free. Preferably the adhesive is formed of a weight ratio of solid rubber to liquid rubber of about 1:0.5 to about 1:7. When a thermoplastic rubber is used, an endblock associating resin can also be used with the block copolymer solid rubber composition for improving adhesion and hold properties of the composition. A minor amount of tackifier can be added without affecting the improved properties of the present invention. The adhesive can preferably be cross linked with a sulfur, sulfur-bearing agents, peroxide, isocyanate or an aluminum isopropylate composition. These adhesives exhibit improved adhesion in cold weather and oily surface applications and other properties. The pressure sensitive adhesives can be used in health care, industrial and drug delivery systems. The adhesives can be processed by a hot melt process for providing improved ecological benefits.
