Publication number: 20140275467Abstract: The present invention is directed to a novel polymerization process for making novel absorbable, linear polylactone polymers prepared using novel polymerization initiators to achieve rates of mechanical property loss or of absorption of articles made from the polymers that are at least about 1.2 times faster than the rates of mechanical property loss of polymers made by similar processes utilizing conventional initiators. The novel polymerization initiators include monols or diols possessing at least one primary alcohol group and two or more carboxylic acid groups. The invention also is directed to absorbable polylactone polymers prepared by processes of the present invention and to medical devices made from such polymers.Type: ApplicationFiled: March 3, 2014Publication date: September 18, 2014Applicant: Ethicon, Inc.Inventors: Dennis D.

Patent number: 7148315Abstract: Monomer addition methodology is provided to adjust monomer addition rates to a polymerization reactor. Advantages of the invention include control of bioabsorbable copolymer structure, improvement of monomer conversion, control of reaction temperature, and reduced reaction time. The overall result is an improved process and enhanced product performance. The technology is particularly useful in the copolymerization of monomers with different reactivity ratios, such as glycolide/lactide copolymers and glycolide/caprolactone copolymers. Monomer reactivity ratios and reaction kinetics are utilized to adjust monomer addition rates.Type: GrantFiled: October 23, 2002Date of Patent: December 12, 2006Assignee: Ethicon, Inc.Inventors: Modesto Erneta, Terry E.

Patent number: 4574066Abstract: Melt extruded poly(6-oxy-2-naphthoate-4-oxybenzoate) shaped articles of relatively high strength and modulus are produced in a lesser period of time than commonly heretofore required in the prior art. The required polymer is capable of exhibiting an anisotropic melt phase and is formed through the reaction of 6-acetoxy-2-naphthoic acid and 4-acetoxybenzoic acid under a combination of melt polymerization conditions which surprisingly has been found to yield a shaped article following melt extrusion which may be heat strengthened in an unusually brief period of time (i.e. two hours or less). The polymerization is catalyzed by a potassium salt (e.g. potassium acetate), and the polymerization conditions require a relatively highly elevated final polymerization temperature. Substantially all of the acetic acid by-product is removed from the polymerization zone prior to concluding the polymerization under reduced pressure conditions.Type: GrantFiled: February 27, 1984Date of Patent: March 4, 1986Assignee: Celanese CorporationInventors: John D.
