- Abstract
- Currently, polyurethane hot-melt adhesives based on urethane prepolymers containing terminal isocyanate groups are predominantly used as binders for rubber crumb. In this study, urethane prepolymers were synthesized using polypropylene oxide with a molecular weight of 2000 and polysocyanates of both aromatic and aliphatic nature. The urethane prepolymers were modified using a metal-complex system, leading to the structuring of the polyurethane binders. As a result, a twofold increase in the strength and elasticity of the polyurethanes was achieved, along with improved heat resistance.
