    摘要: The adhesive characteristics of cured sealant formulations based on polysulfide polymers are substantially improved by the incorporation of glycidyl trialkyloxysilanes. The glycidyl trialkyloxysilanes provide an extremely high peel strength for coatings on various substrates, especially aluminum. The amount of curing agent required is reduced when glycidyl trialkyloxysilanes are used as adhesion-promoting additives.

    摘要: Soluble solid easily handled polyepoxide polymers can be formed from 4-vinylcyclohexene diepoxide in a catalytic process using a tertiary amine and an active hydrogen containing compound. The powdery polymers of the invention can be easily cured to thermoset resins using coreagents to form castings, laminates, and coatings having exceptional toughness and good strength.
