摘要：
The present invention discloses reworkable epoxy compositions suitable for encapsulation of and underfill for electronic components comprising (a) a curable epoxy component which is the reaction product of an epoxidized 1-alkenyl ether or 1-cycloalkenyl ether and a polycarboxylic acid, the reaction product being substantially free of unreacted acid or acid impurities; and (b) a curing agent for the epoxy component, wherein the reaction products of the epoxy composition are reworkable. The cured epoxy compositions of this invention contain thermally labile weak α-alkoxy ester linkages which provide for the reworkable aspect of the invention.
