Abstract:
An article of manufacture, comprising: a second polymeric product formed by 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 the second polymeric product, wherein the continuous polymerization and condensation process is conducted such that the first polymeric product is charged continuously into the secondary reactor and the second polymeric product is withdrawn continuously from the secondary reactor, and further wherein the article of manufacture is selected from the group consisting of an overprint varnish, a coating, a weatherable coating, a coating modifier and compatibilizer, a dispersant, a polymer surfactant, and a paint.
