dc.description.abstractAcrylic pressure-sensitive adhesives obtained by emulsion polymerization are environmental friendly adhesives. The monomers chosen were butyl-acrylate, acrylic acid, 2-ethylhexyl acrylate, methyl methacrylate, and 2-hydroxyethyl acrylate. The effect of varied monomer composition on adhesive performance is studied. The particle sizes of adhesives were measured by using CILAS 1180 Laser Particle Size Analyzer. ATR-FTIR spectroscopy was used to determine the wave number of acrylate emulsions obtained. The adhesives obtained with constant thickness were coated onto a Kraft paper and evaluated for adhesive performance by measuring their loop tack, peel strength and dynamic shear strength. With increasing of MMA and AA content, peel strength was found to increase and loop tack decreased. Hydrogen bond formed through the carboxylic acid functional group increased the peel strength. As the MMA content increased, the latex gel fractions were found to decrease. With decreasing of gel fraction, dynamic shear strength was found to decrease. As the 2- EHA content increased, dynamic shear strength and peel strength were found to increase. Peel strength and dynamic shear strength showed an increase with decreasing of particle size.en_US
