Emulsion polymer having a vesiculated structure and the process for preparing the same |
摘要 |
A process for preparing an emulsion polymer comprising placing a first mixture of monomers in a feed tank B which is connected directly to a reactor, placing a second mixture of monomers in a feed tank A which is connected to the feed tank B, and continuously varying the composition ratio of the monomers of feed tanks A and B in the emulsion polymer. The composition ratio is varied by varying the rate of feeding of the second mixture of monomers present in tank A into tank B while simultaneously varying the rate of feeding of the first mixture of monomers present in tank B into the reactor. The polymerization occurs as the first and second mixtures of monomers are simultaneously fluxed in the reactor while stirring.
