p-Nonylphenol/o-cresol/cyclohexanone/formaldehyde resins as modifiers in pressure sensitive compositions

Polimery 2003, No 11-12, 774


DOI: dx.doi.org/10.14314/polimery.2003.774


Summary

The preparation, in basic catalyzed polycondensation, of heat reactiye p-NPh/o-CR/CHX/p-FA resins at yarious molar ratios of monomers has been described. The resins thus obtained were characterized by 1H NMR and infrared spectroscopy and were used as crosslinking components in pressure sensitive formulae. The presence of these polymers in PSA's composition of rubber or acrylic type, imparted after curing a high cohesive strength, without affecting significantly the adhesive strength. Such compositions are useful for the laminates working at high temperature.
