The product are polyethers synthesized with new catalyst, characterized by low unsaturation, narrow molecular weight distribution, high activity and high primary hydroxyl content. They widely used in high elastic resilient cold cure,microporous elastomer and semi-rigid polyurethane foam plastics. Compared with conventional polyethers, they show wider practicability, stronger tear resistance, better deflection and elongation rate.
