Ethyl acrylate(EA) and butyl acrylate(BA) were employed to modify the diglycidyl ether of bisphenol A(DGEBA)-methyltetrahydrophthalic anhydride(MeTHPA) epoxy system via in-situ polymerization.The sea-island structure is observed from the SEM micrographs of the DGEBA-MeTHPA system modified by polyacrylates.By the addition of 10%(mass fraction) EA and BA,the tensile strength of the epoxy system reduces by 9.51% and 4.00%,and the modulus reduces by 14.81% and 9.52%,respectively.The glass transition temperature...
