Abstract

The present invention relates to a resin composition, a separation membrane for a secondary battery which is manufactured by using same, and a secondary battery which is applied with the separation membrane, and the resin composition of the present invention comprises: a photoinitiator for absorbing wavelengths in the range of 100~400nm; and a connecting material having two or more vinyl groups. In addition, the present invention provides a fine porous polymer separation membrane having excellent mechanical strength, heat resistance, and heat shrinkage by inducing a photocrosslinking through an exposure process after manufacturing a porous separation membrane through extrusion/annealing/drawing/heat setting by using the resin composition, and the present invention further provides a secondary battery which is applied with the separation membrane.
