Abstract: Expandable bladders for use in curing presses for hydrocarbon rubbers, such as pneumatic tires, are a crosslinked elastomer composition including isobutylene repeat units. When PTFE and/or graphite is present, they can be cured with brominated phenolic resins in shorter periods of time. The fluorinated ethylene polymer is added in particulate form and thereafter dispersed throughout the bladder. The fluorinated ethylene polymer may or may not form fibers.

The bladders generally have enhanced lubricity, reduced adhesion to cured tire innerliners, better resistance to cracking during flexing, and have lower tension set than similar compositions without fluorinated ethylene polymers. The above enhancements allow hydrocarbon rubbers such as tires to be molded with fewer defects caused by abraded or deformed bladders. They also enhance the useful life of the bladder reducing the cost of tire curing.

Abstract: A hydrophilic coating composition used to impart increased lubricity and wettability to the surface of a hydrophobic substrate which is comprised of three essential components:1) Hydrogel-forming polymer component A2) Water-soluble polymer component B3) Common solvent C for the components A and BThe water-insoluble, hydrogel-forming component A consists of a segmented copolymer with long, hydrophilic terminal blocks and the essentially hydrophobic central section. The two polymer components A and B have a limited miscibility in the absence of a common solvent C. Therefore, their blend tends to separate spontaneously into two polymer phases.
