Latest Patents

Harri Heikkinen holds a patent for a "Method for preparing glycolide polyester by ring opening polymerization." This invention relates to a method for preparing a glycolide polyester characterized by the use of a glycolide monomer, with optional co-monomers of cyclic esters, subjected to ring opening polymerization. The process involves a dispersion stabilizer and a catalyst that precipitates glycolide homopolymer or copolymer from the solvent. The solvent is selected to ensure that the glycolide monomer and co-monomers, along with the stabilizer and catalyst, are soluble, while the resulting glycolide homopolymer or copolymer remains non-soluble.
