A preparation method and uses of a high-performance water-soluble acrylic resin with high solid content and low viscosity. The method polymerizes the free radical solution in a mixed solvent by a continuous method to produce an acrylic resin and the resin is rendered water-soluble through salification. Modification with versatate introduces a large branched structure. Silicone functional monomer is used to modify the acrylic resin. Amino resin is used as a curing agent to directly prepare a waterborne amino-acrylic coating with a simple process, and the coating has good hardness, fullness, water and alcohol resistance and salt spray resistance.

Processes and apparatus for preparing bimodal polymers are provided. In some embodiments, processes include introducing a monomer, a first diluent, a catalyst, hydrogen, at a first hydrogen concentration, and optional comonomer, to a first loop reactor to produce, under polymerization conditions, a first slurry of polymer solids. Processes may also include continuously discharging the first slurry of polymer solids from the loop reactor as a first polymerization effluent to a first flash tank; separating the first polymerization effluent in the first flash tank to provide a first concentrated polymer slurry with significantly lower hydrogen concentration; and transferring the first concentrated polymer slurry from the flash tank to a re-slurry mixer. Processes may further include introducing a re-slurry mixer diluent to the first concentrated polymer slurry to form a second concentrated polymer slurry in the re-slurry mixer that can be pumped to a second slurry loop reactor.
