Abstract
The present invention provides in a bulk polymerization reactor chain suitable for polymerizing a syrup of one or more monomers having dissolved therein one or more rubbers the improvement comprising a uniform shear field device. During polymerization at least a portion of the syrup polymerized to from 4 to 95% conversion passes through the uniform shear field device to produce at least a portion of a syrup having a rubber particle size more closely controlled than currently possible using a conventional reactor chain without a uniform shear field device.
