Abstract:
The invention is a resin composition containing following polymer (A) and polymer (B), wherein a content of the polymer (A) is 1 to 80 wt% based on the total weight of the polymer (A) and the polymer (B). Polymer (A): an alicyclic structure-containing hydrogenated polymer having a heat distortion temperature of 170°C or higher Polymer (B): a polymer incompatible with the polymer (A) and having a heat distortion temperature of lower than 170°C, and A microporous film formed by using the resin composition, and A separator including the microporous film, and A secondary battery having the separator. One aspect of the invention provides a resin composition suitably used as a raw material for a separator of a secondary battery excellent in safety, a microporous film obtained by forming the resin composition, a separator including the microporous film, and a secondary battery having the separator.
Abstract:
Composition comprises: 1-70 wt.% of at least one copolymer obtainable by polymerizing a mixture of monomers comprising (i) at least one ethylenically unsaturated monomer, which comprises at least one radical of carboxylic acid, carboxylic salt, carboxylic ester, carboxylic amide, carboxylic anhydride or carboxylic imide, and (ii) at least one ethylenically unsaturated monomer having a polyalkylene oxide radical; 0.01-10 wt.% of at least one emulsifier; and 29-98 wt.% of at least one hydrocarbon liquid at 20[deg] C or a hydrocarbon mixture.
