Abstract

An acrylate tackifier was prepared for producing high performance acrylic pressure-sensitive adhesives (PSAs). PSAs exhibiting high adhesion values were prepared using 2-ethyl hexylacrylate (2-EHA), 2-carboxyethyl acrylate (${\beta}$-CEA), and acrylic acid (AA) monomers. The acrylate tackifier was prepared using an acrylic monomer for improving its compatibility with the acrylic PSA. The weight-average molecular weights of PSA and the acrylate tackifier were found to be around $1.2{\times}10^6g/mol$ and 20,000-40,000 g/mol, respectively. Physical properties (such as the peel strength, tack, and the holding power) of the mixtures of acrylic PSA with different acrylate tackifiers were enhanced with an increase in the amount of tackifier added.
