Acrylic resin emulsion with high heat resistance, polymeric composition thereof and method for preparing the same

A polymeric composition for forming an aqueous acrylic resin with high heat resistance, comprising a monomer composition and a reactive emulsifier, wherein based on 100 wt % of the monomer composition, the monomer composition includes:

• 92 to 98 wt % of at least one first monomer, the first monomer being selected from the group consisting of methyl methacrylate, ethyl acrylate, propyl methacrylate, butyl acrylate, isobutyl methacrylate, pentyl methacrylate, hexyl methacrylate, heptyl methacrylate, octyl methacrylate, 2-ethylhexyl methacrylate, n-octyl methacrylate, iso-octyl methacrylate, nonyl methacrylate, decyl methacrylate, lauryl methacrylate, octadecyl methacrylate, methoxyethyl methacrylate, n-butyl methacrylate, 2-ethylhexyl acrylate, and ethoxymethyl acrylate;
• 1 to 4 wt % of at least one second monomer, the second monomer being selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, fumaric acid, itaconic acid, butenoic acid, and maleic anhydride;
• 1 to 5 wt % of a third monomer, the third monomer being selected from the group consisting of vinyl acetate, styrene, methyl styrene, vinyl toluene, methacrylonitrile, diacetone acrylamide, N-hydroxymethyl acrylamide, cyclohexyl methacrylate, and isobornyl methacrylate;
• 1 to 5 wt % of at least one of a hydroxyl group containing acrylic polyester polyol and a hydroxyl group containing acrylic polyether polyol;
• and
• 1 to 5 wt % of an alkoxysilane.
