Abstract: The adhesive of the present invention includes latexes with an adhesion promoter which is preferably polyamidoamine. The addition of the polyamidoamine improves the adhesive strength between substrates such as between two plastic films or between a plastic film and paperboard. The present invention also provides for an adhesive prepared from a latex which is neutralized with a particular base and a hydrophobic polyamidoamine having particular amine values and viscosity whereby the strength of the adhesive bond is increased in humid conditions. The present invention also provides for adhesives primarily for use in laminate structures which are exposed to highly humid conditions. The adhesive is a polymeric latex based system to which a polymeric adhesion promoter like polyamidoamine and an epoxy emulsion are added. The adhesive retains bond strength when exposed to humidity.

Abstract: A biscyclobutarene monomer is prepared having two cyclobutarene moieties bridged by a divalent radical having at least one azo linkage. The monomers can be polymerized to form polymers exhibiting outstanding thermooxidative stability at high temperatures for prolonged time periods.
