摘要
A vinylidene chloride polymer powder, having a second order transition temperature of at least 50 DEG C, is recovered from a latex and dispersed with moderate shear in a non-solvent for vinylidene chloride polymers, such as a polyol used in the preparation of polyurethane materials. A dispersion of the powder and a polyol is eminently suitable for use in the preparation of polyurethane foams to impart enhanced flame retardancy and load-bearing properties thereto.
