Abstract:
A process for the preparation of polymers comprising the steps of:a) providing a compound selected from the group consisting of dicyclopentenyloxy acrylate, dicyclopentenyloxy methacrylate, dicyclopentenyloxyethyl acrylate, and dicyclopentyloxyethyl methacrylate; b) providing a solvent selected from the group consisting of water, acetone, methanol, isopropanol, propionic acid, acetic acid, toluene, hexane, ethyl acetate, methylethyl ketone, dimethyl formamide, dimethylsulfoxide, and combinations thereof, c) providing an initiator; d) forming a reaction mixture by admixing the solvent, the initiator, and the compound selected from the group consisting of dicyclopentenyloxy acrylate, dicyclopentenyloxy methacrylate, dicyclopentenyloxyethyl acrylate, and dicyclopentyloxyethyl methacrylate; and e) passing the reaction mixture through a heated zone wherein the reaction mixture is maintained at a temperature of at least 175Â° C. for from 0.1 seconds to 300 seconds to form a liquid polymer with a number average molecular weight of from 450 to 10,000.
