Solid acrylic resin using a continuous tube reactor |
摘要 |
Described is a process for making acrylic resins suitable as polymeric surfactants used in emulsion polymerization, as pigment grinding resins and for preparing dispersions used as overprint varnishes. The feedstock is styrene, alpha-methyl styrene, acrylic acid and a polymerization initiator and is preferably free of solvent. This mix is passed through a continuous tube reactor run at a controlled range of pressure and relatively low residence time and temperature. Optimally, when the polymer/unreacted monomers blend exits the reactor and is devolatilized, the recovered monomers are used to make up part of the feedstock.
