Patent number: 8846853Abstract: A direct polycondensation method for medical biodegradable polylactic acid (PLA).

Instead of tin catalysts having cytotoxicity, the catalyst used in the invention has high biocompatibility and biosafety. The synthesized PLA does not contain any metal and other toxic components; therefore, it can be used as the carrier for targeting drugs and controlled release drugs. The green catalyst and green processing method (no solvent applied and no toxic products produced) are used to synthesize the green biodegradable PLA with high biosafety. The molecular weight distribution for all synthesized products is narrow and the molecular weight is controllable within 1.5-3.0×104.Type: GrantFiled: November 3, 2011Date of Patent: September 30, 2014Assignee: Nanjing UniversityInventors: Hong Li, Quanxing Zhang, Wei Jiang, Wei Huang, Bingcai Pan

Patent number: 8697832Abstract: The invention relates to a process for preparing lactic acid polymers of highly crystallinity and molecular weight, the process comprising melt polymerization of a lactide to form prepolymers having active end groups followed by solid state polymerization. The polymerization is carried out in the presence of a catalyst complex comprising a lactide, an organic metal-oxo compound and a lactic acid oligomer. The residual lactide after the melt polymerization is removed by heating the reaction mixture in the temperature range of 98° C. to a temperature less than the melting point of the prepolymer. The metal to oligomer ratio in the catalyst complex is in the range of 0.1 to 10, preferably in the range of 0.5 to 5, more preferably in the range of 0.8 to 1.5.Type: GrantFiled: April 4, 2008Date of Patent: April 15, 2014Assignee: Indian Institute of Technology, BombayInventors: Hemant Nanavati, Vimal Katiyar
