Abstract (en)

[origin: WO0105843A1] A process is disclosed for a continuous, high temperature polymerization process for preparing a free radically polymerized epoxy-functional polymeric product. The process comprises continuously charging into a reactor at least one epoxy-functional acrylic monomer, and optionally at least one non-functional free radical polymerizable monomer. An optional free radical polymerization initiator may also be added. The reactor is maintained at an effective temperature for an effective period of time to cause polymerization of the monomers into a polymeric product, such that the polymeric product is formed substantially free of gel particles. A clear coating is also disclosed incorporating polymers of the present invention, such that the clear coating has a low Delta b value at standard conditions.
