| titleOfInvention | Implementation method of reversible addition fragmentation chain emulsion polymerization |
| abstract | The invention discloses an implementation method of reversible addition fragmentation chain emulsion polymerization. 20-40 parts by weight of water, 0.1-2 parts by weight of bipolar macromolecule reversible addition fragmentation chain reagent, 1-20 parts by weight of monomer and 0.005-0.2 part by weight of micromolecule reversible addition fragmentation chain reagent are added into a reactor, stirring to be uniform is carried out, stirring is carried out, nitrogen is led in, heating is carried out until the temperature is increased to be 50-80 DEG C, 0.004-0.08 part by weight of water soluble initiator is added, initiated polymerization is carried out for 10-60min, 0-2 parts by weight of alkaline aqueous solution is added, and polymerization is continued for 0.5-5h. The invention utilizes bipolar macromolecule reversible addition fragmentation chain reagent with special structure as emulsifier and chain transfer agent, micromolecule reversible addition fragmentation chain is combined with emulsion polymerization, alkali is replenished, so as to improve the stability of emulsion; besides, process is simple, energy consumption is low, reaction time is short, conversion rate is high, no traditional emulsifier is adopted, molecular weight is consistent with design value, and molecular weight distribution is less than 2.0, thus having good industrialization prospect. |
