Abstract:
1. A process including the steps of: a) introducing a feed stock containing at least one monomer and at least one activatable initiator into a recirculating loop reactor having partially polymerized material recirculating therein to form a reaction mixture; b) heating the reaction mixture to at least the activation temperature of the initiator to produce a polymerized intermediate; c) recirculating a portion of the polymerized intermediate through the loop reactor while directing a remaining portion of the polymerized intermediate into a removal stream; d) cooling the recirculating portion of the intermediate to a temperature below the activation temperature of the initiator; e) mixing the cooled recirculating portion of the intermediate with the feed stock; and f) subjecting the remaining portion of the polymerized intermediate to further reaction to form polymerized product.
