Abstract
We synthesized polyurethane elastomer containing acid groups. We measured the adhesion, grip, tensile strength and mechanical properties. Casting polyurethane elastomers were prepared with the contents of acid. The adhesive strength and the wet slip were increased. Also, the tensile strength and abrasion properties were increased. We measured the properties with different acid contents. Increasing the acid content, the mechanical properties were increased. But the mechanical properties were decreased above 0.20 wt% of acid content. The wet slip was increased and the contact angle was decreased as the acid content increased.
