Preparation and Properties of poly (n-butyl acrylate)/ poly (methyl methacrylate-co-styrene) Emulsion Polymer with Pentaerythritol Triacrylate as a Cross-Linking Agent

Abstract:

A series of cross-linking core-shell structured poly (n-butyl acrylate) /poly (methyl methacrylate-co-styrene) emulsion polymer were prepared by semi-batch seeded emulsion polymerization with pentaerythritol triacrylate (PETA) as a cross-linking agent. The emulsion polymers were characterized by Fourier transform infrared spectra (FTIR) and transmission electron microscope (TEM), respectively. The influences of cross-linking agent content on the water resistance and mechanical properties of the emulsion films were investigated. The films prepared by the emulsion polymer with the cross-linking agent exhibited excellent water resistance, and mechanical properties (tensile strength and flexility), resulting from the cross-linking structure of shell segments compared with that prepared without cross-linking agent. The film of the emulsion polymer with 1.0wt% cross-linking agent exhibited better comprehensive performance.
