Síntese e caracterização de látices acrílicos reticulados com (1,6-diacrilato propoxilato hexanodiol) via polimerização em emulsão

Latices based on acrylic acid and ethyl methacrylate, crosslinked with 1,6‐propoxylate‐hexanodiol diacrylate were synthesized via emulsion polymerization with different monomeric compositions. The resultant latices were thickened with different NaOH/(acrylic acid) molar ratios and were characterized by titrimetry, zeta potential measurements, turbidimetry, and capillary viscometry. Intrinsic viscosity was determined for an uncrosslinked copolymer, using toluene as solvent. All the latices were coagulated with NaCl and washed with water at 60°C analyzed by FTIR spectrophotometry, in order to characterize functional groups from the copolymer and crosslinking agent.
