Low-viscous, stable polymer dispersions and polyurethanes prepared therefrom |
摘要 |
Low-viscous, stable polymer dispersions are prepared by blending a hydroxy-containing finely divided solid polymer with a polyol having an equivalent weight between 500 and 10,000. The resulting dispersions are particularly useful in the preparation of polyurethanes having enhanced physical properties particularly load bearing or hardness, tensile strength and tear resistance.
