In-situ anionic continuous dispersion polymerization process |
| abstract |
In accordance with the present invention, a continuous polymerization process is provided for the preparation of a rubbery copolymer by the non-aqueous dispersion random polymerization of a mixture of 30 to 65% by weight of a conjugated diolefin monomer, preferably butadiene, and 35 to 70% by weight of a vinyl substituted aromatic monomer, preferably styrene, in a liquid aliphatic hydrocarbon dispersion medium with an anionic initiator catalyst system in the presence of a block copolymeric dispersing agent which is continuously prepared in-situ. At least one block of the dispersing agent is continuously prepared prior to the dispersion polymerization reaction and a second block of the dispersing agent and a rubbery copolymer are continuously prepared in-situ during the dispersion copolymerization. The second block of the dispersing agent has the polymer structure of the continuously produced rubbery copolymer. |
