Abstract:
A continuous polymerization and condensation process, comprising:(a) continuously charging into at least one primary reactor: (i) at least one radically-polymerizable monomer having a radically polymerizable group and also having at least one condensation reactive functionality; (ii) at least one modifying agent having at least one functional group capable of reacting with the condensation reactive functionality on the radically-polymerizable monomer, wherein at least one of the modifying agents is not a monohydroxy alcohol; (b) maintaining an effective temperature in the primary reactor to cause polymerization of the monomer and to allow at least a portion of the condensation reactive functionality to react with the functional group of the modifying agent, wherein a first polymeric product is produced which incorporates at least some of the modifying agent and the polymeric product is formed substantially free of gelation; (c) charging the first polymeric product into at least one secondary reactor; and (d) maintaining an effective temperature in the secondary reactor to form a second polymeric product, wherein the continuous polymerization and condensation process is conducted such that the at least one radically-polymerizable monomer is charged into the at least one primary reactor while the first polymeric product is simultaneously removed from the at least one primary reactor.
