Abstract
Abstract Silane coupling agents having improved resistance to oxidative and or hydrolytic stress are obtained by mixing an aminoalkyl-substituted hydrolyzable silane and an aryl-substituted hydrolyzable silane. The mixture of silanes is useful for bonding an organic resin to a solid inorganic material and is particularly useful for preparing improved high-temperature composites, such as polyimide/glass fabric laminates.
