Abstract: An adhesive composition containing a polyvinyl alcohol-stabilized butadiene polymer latex and a methylene donor compound. The butadiene polymer latex is prepared by an emulsion polymerization in the presence of polyvinyl alcohol. The adhesive composition may also contain other optional ingredients such as a supplemental polymeric film-forming component, a nitroso compound crosslinker, a maleimide compound crosslinker, a vulcanizing agent, and an acid-scavenging compound. The polyvinyl alcohol-stabilized butadiene polymer latex and methylene donor compound combine to provide a tightly crosslinked, robust film which provides for excellent adhesion and environmental resistance.

Abstract: Polyurethane compositions including the reaction product of a polyurethane prepolymer component including (a) at least one isocyanate-terminated polyalkadiene prepared by capping hydroxy-terminated polyalkadiene having a molecular weight from about 1500 to about 5000 grams per mol (g/mol) with isocyanate; and (b) at least one additional isocyanate-terminated polyalkadiene prepared by capping hydroxy-terminated polyalkadiene having a molecular weight from about 500 to about 1500 g/mol with isocyanate with a curative component. The compositions exhibit numerous useful properties, such as low glass transition temperature (Tg) high temperature stability, low viscosity at room and elevated temperatures, flexibility and flat dynamic mechanical properties versus temperature.

Abstract: An adhesive composition containing a linear polyester polyurethane, a halogenated polyolefin, an epoxy/silane adduct, a Diels-Alder adduct of a halogenated cyclic conjugated diene and a block copolymer of styrene and butadiene and a crosslinking compound for the linear polyester polyurethane. The adhesive composition is preferably utilized as a two-component adhesive for bonding vinyl polymers such as polyvinyl chloride to various substrates such as glass. The adhesive composition exhibits substantial resistance to environmental conditions without the requirements of a pre-heating step.

Abstract: A butadiene homopolymer latex is prepared by emulsion polymerizing appropriate monomers in the presence of polyvinyl alcohol and a stabilizing solvent. The butadiene homopolymer latices can be prepared without problems of coagulation and can be utilized effectively in adhesive compositions without the use of volatile solvents. Adhesive bonds prepared from the butadiene homopolymer latices also avoid the side effect problems associated with polymers prepared utilizing conventional surfactant-based emulsion polymerization techniques.

Abstract: A butadiene heteropolymer latex is prepared by emulsion polymerizing appropriate monomers in the presence of polyvinyl alcohol and a stabilizing solvent. The butadiene heteropolymer can be a butadiene copolymer or terpolymer prepared from butadiene monomers and comonomers such as .alpha.-haloacrylonitrile and acrylic acid. The butadiene heteropolymer latices can be prepared without problems of coagulation and can be utilized effectively in adhesive compositions without the use of volatile solvents. Adhesive bonds prepared from the butadiene heteropolymer latices also avoid the side effect problems associated with polymers prepared utilizing conventional surfactant-based emulsion polymerization techniques.

Abstract: A Diels-Alder adduct of a halogenated cyclic conjugated diene and a block copolymer of styrene and butadiene which is particularly useful in adhesive compositions. The Diels-Alder adduct has a halogen content of between about 30 and 45, preferably between about 34 and 40, percent by weight. The halogen content of the adduct is crucial to the performance of the adduct in adhesive compositions. Hexachlorocylopentadiene is a preferred halogenated cyclic conjugated diene for preparing the adduct and either diblock or triblock styrene-butadiene copolymers may be utilized.

The adhesive contains a Diels-Alder adduct of a perhalogenated cyclic conjugated diene and an olefinically unsaturated dienophile having a vinyl content in excess of 50 percent, a phenolic resin, an aromatic hydroxy compound, a formaldehyde donor, a heat-activated unsaturated elastomer crosslinker, a vulcanizing agent, and a metal oxide. An adhesive bond prepared with the adhesive is resistant to high temperature fluids and corrosive agents.
