The basic chemical reactions, used to synthesize monomer and polymer resins and the chemistry involved in the use of curing agents to polymerize the resins, have been extensively studied and are well documented. This section serves as a summary only of those polymers that are primarily used in adhesives formulations for electronic applications. Among these polymers are the epoxies, silicones, polyurethanes, polyimides, acrylates, cyanate esters, and cyclo-olefins. Further technical detail for these polymers maybe acquired through literature searches in the transactions of the American Chemical Society (Polymer Group), Society of Plastics Engineers (SPE), and the Society for the Advancement of Materials and Process Engineers (SAMPE).

The adhesives described above are limited in their resistance to elevated temperatnres for prolonged periods because of depolymerization or decomposition reactions at temperatures greater than 120-150°C. High temperature resistant structural adhesives based on polyimide, cyanate ester and bis-maleimide chemistries can withstand the higher temperatures but require more difficult cure conditions, are generally more expensive and service a smaller specialist segment of the overall sttuctural adhesive market.
