A process for preparation of protective colloid stabilized emulsifier-free aqueous dispersions based on at least two monomers selected from vinyl aromatics and 1,3-dienes in the presence of adjuvants, optionally other monomers, in amount 0.1-20 wt.%, and on 60-80 wt.% reaction, 0.01-0.4 wt.% oil soluble regulator is added to the reaction vessel, and on 80-95% reaction a further 0,01-0,4% of oil soluble regulator is added. |
