Abstract

Pressure sensitive adhesives (PSAs) based on acrylic monomers was synthesized. For this purpose emulsion,
polymerization process was conducted for the preparation of an acrylic copolymer containing 2-ethylhexylacrylate,
vinyl acetate, methacrylic acid (MAcid), and acrylonitrile using potassium persulfate as an initiator. The
monomers were feeding different ratios with increasing 2% and 4% MAcid and acrylonitrile. The adhesive
properties have been evaluated in terms of viscosity, solid content, glass transition temperature (Tg), peel strength,
and shear strength value for all samples. It was observed that trends peel strength and shear strength variations
are correlated with the changing parameters. The synthesized PSAs show good adhesive properties and could
be easily peeled off from the surface BOPP and stainless steel. These samples with satisfactory adhesion were
characterized by Universal Testing Machine. Fourier transforms infrared, differential scanning calorimeter.
