摘要:
A process for preparing aqueous primary dispersions comprising at least one hydrophobic polyurethane obtainable in miniemulsion by reacting (a) at least one polyisocyanate and (b) at least one compound containing at least one isocyanate-reactive group in the presence of a catalyst.
摘要:
Hybrid dispersions comprising polyadducts and free-radical addition polymers, obtainable by first emulsifying the constituent monomers of said polyadducts and polymers in water and then conducting the polyaddition to prepare the polyadducts and the free-radical addition polymerization to prepare the polymers, the respective monomers being emulsified in water before 40% of the monomers of which the polyadducts are composed have reacted to form such polyadducts.
