Abstract

Polyurethane resin was especially mixed with polybutadiene rubbers which had each other different molecular structures and functional groups. Liquid and cure properties were tested experimentally for mixtures. Viscosity of mixtures and drying time were influenced by solubility of thinner and reactivity of rubber. Adhesive strength represented maxium at rubber content $15{\times}22%$ (Wt. % ), and rapidly decreased over 25%. DBTDL(di-n-butyltindilaurate) showed the longest stroage stability.
