PREPARING COARSE POLYMER DISPERSIONS |
摘要 |
In a process for preparing coarse polymer dispersions Pg where a mixture M comprising at least one conjugated diene monomer A and at least one ethylenically unsaturated comonomer B is polymerized by free-radical aqueous emulsion polymerization in the presence of an emulsifier E and with or without further additives to form a fine polymer dispersion Pf and said fine polymer dispersion Pf is agglomerated to form a coarse such dispersion Pg, the agglomeration is carried out using a combination of chemical agglomeration and pressure agglomeration; the invention also relates to such coarse polymer dispersions and their use.
