【摘要】 <正> The volume change of the copolymer epoxy resins can be controlled by copolymerizing epoxy resin ESI with 3,9-di (5-norbornene-2, 2)-1, 5, 7, 11-tetraoxaspiro [5, 5] undecane (NSOC). During curing, the volume changes of copolymer epoxy resins with various amounts of NSOC were measured with a dilatometer. Cure process does not produce volume change when epoxy resin E51 : NSOC is 5.88 : 1 in equivalent.
