Abstract
Hydrocarbon resins, which are defined as low-molecular weight, amorphous, and thermoplastic polymers, are widely used as tackifiers for various types of adhesives, as processing aids in rubber compounds, and as modifiers for paint and ink products, and for plastics polymers such as isotactic polypropylene. Typically, hydrocarbon resins are non-polar, and thus highly compatible with non-polar rubbers and polymers. However, they are poorly compatible with polar systems, such as acrylic copolymers, polyurethanes, and polyamides. To overcome this problem, in this study, novel hydrocarbon resins were designed to have a highly polar chemical structure compared to the conventional hydrocarbon resins. And, they were synthesized by copolymerization of dicyclopentadiene (DCPD) monomer and acrylic monomer, and subsequent hydrogenation of the polymerized resin. They are denoted as H2-DCPD-acryl resin. To synthesize of acrylic-monomer-modified hydrocarbon resin each acrylic monomer was polymerized with DCPD monomer. Methyl methacrylate, butyl methacrylate, tert-butyl acrylate, and acrylic acid contributed to high yields of polymerization and to the increase in the softening point (S.P.) of the resin. The total concentration of the acrylic monomer and the chemical structure of the synthesized resin were estimated by spectroscopic techniques such as FT-IR, 1H NMR, and pyrolysis-GC/MS, and by the analysis of the oxygen content. Acrylic copolymer based pressure sensitive adhesives were formulated and their performance was analysed. H2-DCPD-acryl resin, hydrogenated DCPD resin, aliphatic C5 resin, and aromatic C9 resin were used as tackifiers for the solvent-based acrylic PSAs. Modification of H2-DCPD-acryl resin for the solvent-based acrylic PSA caused the rolling ball tack to be maintained and an increase in the 180o-peel adhesion strength on the SUS substrate. In particular, the acrylic PSA blended with H2-DCPD-acryl resin showed a considerable increase in the 180o-peel adhesio
