A substantially non-gelled polymeric composition is disclosed and comprises the reaction product of an A polymer which is an addition polymer having 3.5 or more reactive functional groups per polymer chain and a B polymer having about 2 to about 3 functional groups per polymer chain that are co-reactive with the reactive functional groups of the A polymer. Also disclosed is a process for preparing such polymeric compositions, powder coatings and 100% solids ink resins prepared with such polymeric compositions, and a method for deglossing a powder coating using such polymeric compositions.

Non-gelled product of addition and condensation polymers with mutually reactive groups

Powder coating of non-gelled product of addition polymer A and polymer B with mutually reactive groups

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.

Process for the continuous production of epoxylated addition polymers, and powder and liquid coating applications containing epoxylated addition polymers

A process is disclosed for a continuous, high temperature polymerization process for preparing a gel free polymeric product. The process comprises continuously charging into a reactor at least one monomer such that the reactor is filled to 100 percent of its usable volume. 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.
