摘要： A method for the preparation of gel-free poly 2-hydroxyethyl methacrylate substantially in the absence of a chain transfer agent, comprising introducing monomeric 2-hydroxyethyl methacrylate containing ethylene glycol dimethacrylate impurities in the range of about 0.05 to 0.1% by weight into alcohol, polymerizing the 2-hydroxyethyl methacrylate to form a polymerization mixture, and removing the alcohol. Hydrophilic pressure sensitive adhesives are provided by adding polyethylene glycol to the polymerization mixture prior to removing the alcohol. A method for the preparation of an acrylic emulsion ink jet receptive clear coating, comprising forming a alkyl acrylate monomer-containing pre-emulsion feed mixture, introducing an activator into the alkyl acrylate monomer-containing pre-emulsion feed mixture, reacting a water soluble monomer feed in the alkyl acrylate monomer-containing pre-emulsion feed mixture, the water soluble monomer feed comprising 2-hydroxyethyl methacrylate and a cationic monomer to form a clear polymer in the reaction mixture. In another embodiment, the clear polymer in the butyl acrylate-containing pre-emulsion feed mixture is subsequently reacted with a water insoluble monomer feed mixture comprising 2-hydroxyethyl methacrylate, n-vinyl pyrrolidone, butyl acrylate, and methacrylic acid to form a second clear polymer in addition to the clear polymer in the alkyl acrylate monomer containing pre-emulsion feed mixture.
