 ABSTRACT

Pressure sensitive adhesives containing resinic acid derivatives in their structure were synthesized. The insertion of resinic acid derivatives as pendant group was carried out to improve the cohesive strength of acrylic polymers. IR, 1H-NMR spectroscopy and other methods were used to characterize the monomers and polymers. The inherent viscosity of the polymers was found to be is in the range 0.16-0.81 dL/g and the energy of thermal decomposition in the range 42-156 kJ/mol.

 Key Words: pressure sensitive adhesives, resinic derivatives, adhesive and cohesive strength, thermal properties.
