Abstract: An adhesive composition using as the primary binder an emulsion of butadiene-vinylidene chloride copolymer is disclosed. The composition is particularly suited for binding rubber to metal in a variety of uses such as vibration damping devices. The adhesive composition has resistance to hot water and or water glycol solutions.

Abstract: Coating compositions are disclosed which use a polyoxetane polymer having CH.sub.2 --O---CH.sub.2 --R.sub.f side chains where R.sub.f is a highly fluorinated alkyl or polyether. The coating compositions use polyisocyanates to create isocyanate terminated polymers from the poly(oxetanes) and from various polyols from alkylene oxides or polyester polyols. These can be reacted together to form block copolymer structures or can be linked together when the coating is crosslinked. A preferred method is to use blocked isocyanate groups. Another preferred embodiment is to use the composition as a abrasion resistant coating for glass run channels.

Abstract: Disclosed is a water-based adhesive with enhanced effectiveness for bonding metal and rubber substrates for uses such as vibration damping devices. The adhesive is formulated from a latex which includes at least one conjugated diene and a macromonomer containing at least two ethylene oxide repeat units.

Abstract: A hollow rubber play ball is disclosed that uses a combination two or more fillers to produce desirable playing properties in a tennis ball as specified by the International Lawn Tennis Federation (ITF). The preferred play ball is a pressureless tennis ball. The specific fillers disclosed are mineral type particulate reinforcing fillers such as silicas and carbon black, polymeric fillers such as cellulose, a reaction product of grafting polyethylene with cellulose, and ethylene-vinyl acetate copolymers. These fillers can also have surface treatments to enhance the elastomer-filler interaction. Another reinforcing filler that can be introduced with the rubber components is the non-rubber constituents in skim rubber that serve to increase the modulus of a compounded rubber.

Abstract: A urethane coating composition is disclosed which uses fluorinated monohydric alcohols to increase abrasion resistance. One specific use of the coating is on vehicle sealing systems which use elastomeric substrates. The coating composition was found to have dramatically improved abrasion resistance in glass run channel applications over similar coatings without the fluorinated component.

Abstract: Hydroxy-terminated telechelic rubber polymers and block copolymers of flexible polymers with unsaturated polyester resins improve the elongation and flexural elongation of in-mold coating compositions for fiber reinforced plastics (FRP). An FRP in-mold coating composition based upon vinyl ester resin, ethylenically unsaturated monomers, and at least one of telechelic hydroxy terminated flexible polymers and the block copolymers of functionally terminated flexible polymers with unsaturated polyester polymers are described.

Abstract: A block copolymer of generally an AB, ABA, or A(BA).sub.n structure, or mixtures thereof where the A block is an unsaturated polyester, the B block is a flexible polymer having a Tg of 0.degree. C. or lower, and n is 2 to 5. The various block components are generally first separately prepared as polymers with the flexible polymer generally having 1 or 2 functional end groups such as an amine group, a carboxyl group, or a hydroxyl group with the later being preferred. Alternatively, for low molecular weight unsaturated polyester blocks, the block can be made in situ. The preferred reaction route is to react a mono or dihydroxy terminated flexible polymer with a diisocyanate which subsequently can be readily reacted with the polyester. The block copolymers can be utilized as toughening agents.

Abstract: Liquid telechelic polymers are made from dienes and are produced via anionic polymerization. While having low molecular weight, for example less than 15,000, the telechelic polymers are generally gel-free, have high amounts of trans-1,4 structure, low vinyl unsaturation and low bulk viscosities. The liquid telechelic polymers are made utilizing a trimetallic initiator comprised of (1) an organopolylithium compound and (2) a complex of a trialiphatic substituted aluminum compound or derivative thereof and a barium salt of an organic alcohol.
