<p>The dienes are polymerised in aqs. soln. in the presence of protective colloids and opt. other aids by a catalyst of gen. formula: R1-CO-R11 (where R1 and R11 are H or (substd.) aliphatic, aromatic, naphthenic gps.). 0.1-20 wt.%, pref. 1-10 wt.% of the catalyst is used and a temp. of 30-85 degrees C, pref. 40-65 degrees C. Pure polymers are obtained in high yield.</p> |
