Title:
METHOD FOR CONTINUOUSLY PERFORMING A POLYMERIZATION OF MONOMERS OR COMONOMERS
Document Type and Number:
WIPO Patent Application WO/2014/191103
Kind Code:
A3
Abstract:
The invention relates to a method for continuously performing a polymerization of monomers or comonomers, in particular a homopolymerization or copolymerization of dienes, such as butadienes, isoprenes, and piperylenes, into polymers in a reactor (1, 1.1, 1.2), in particular in a kneader mixer, having at least one inlet (2) for the product to be polymerized (feed), which inlet is adjoined by a feed zone (3) in the reactor (1, 1.1, 1.2). According to the invention the prepolymerized product is mixed back into the feed flow in the feed zone (3). The feed zone (3) in which the back-mixing occurs constitutes up to 50% (>0 - 0.5 of the product chamber) of the processing length.
