  • Publication number: 20170240698
    Abstract: The present invention is directed to a crosslinked or non-crosslinked polymer particle, wherein the crosslinked polymer particle comprises a copolymer of poly(alkylene glycol-graft-lactate) that is crosslinked by at least one hydrolysable monomer. Another embodiment of the present invention is a polymer particle comprising a crosslinked polymer particle that is a product of starting materials comprising (a) a hydrophilic monomer, (b) a hydrophobic monomer, and (c) a hydrolysable crosslinking agent. Another embodiment of the present invention is a polymer particle comprising, a crosslinked copolymer comprising structures represented by Formulas (I), (II), and (III), where Formulas (I), (II) and (III) are defined in the specification. Yet other embodiments of the present invention include a method of preparing a methacrylate terminated macromonomer, a method of preparing a crosslinking agent, and a method of preparing a therapeutic agent loaded nanosphere by dispersion polymerization.

  • Patent number: 9358211
    Abstract: The present invention is directed to a crosslinked or non-crosslinked polymer particle, wherein the crosslinked polymer particle comprises a copolymer of poly(alkylene glycol-graft-acrylate) that is crosslinked by at least one hydrolysable monomer or crosslinking agent. The present invention is also directed to a polymer particle comprising a crosslinked polymer particle that is a product of starting materials comprising (a) a hydrophilic monomer, (b) a hydrophobic monomer, and (c) a hydrolysable crosslinking agent (the crosslinking agent may be absent in the case of non-crosslinked particles). The present invention is still further directed to a polymer particle comprising a crosslinked copolymer, where the crosslinked copolymer includes structures represented by Formulas (I), (II), and (III), as defined in the specification. Other embodiments of the present invention also include methods of manufacturing polymer particles.
