Abstract

The present invention discloses a water-based acrylic resin with high heat resistance and a polymerizable composition thereof, wherein the polymerizable composition comprises a monomer composition and a reactive emulsifier. Based on 100 weight percent of the monomer composition, the monomer composition comprises an alkyl-containing (meth)acrylate, a carboxyl-containing (meth)acrylic acid, an olefin-unsaturated functional group-containing (meth)acrylate, a grafted polyether polyol SPECFLEX NC701 containing copolymerized styrene and acrylonitrile and / or a hydroxyl-containing polyether acrylic polyol and an alkoxy-containing organosilicon. The water-based acrylic resin with high heat resistance of the present invention can improve the applicability of a water-based treatment agent for surface treatment of synthetic leather.
