Appl. No.:

8/098709

Richard A. Gross - Chelmsford MA
Stephen P. McCarthy - Tyngsboro MA
Michael S. Reeve - Lowell MA

Assignee:

University of Massachusetts Lowell - Lowell MA

International Classification:

C08G 6308
C08G 6384

US Classification:

525411

Abstract:

A biodegradable and hydrodegradable diblock copolymer includes a naturally-occurring poly(. beta. -alkanoate) component and a chemically synthesized polyester component formed by ring-opening polymerization. A method of forming the biodegradable and hydrodegradable diblock copolymer having a poly(. beta. -hydroxyalkanoate) component and a chemically synthesized polyester component includes exposing a naturally-occurring poly(. beta. -hydroxyalkanoate) to alcoholysis and then to a trialkyl metal to form a dialkyl metal poly(. beta. -hydroxyalkanoate) macroinitiator. The macroinitiator is then reacted with a lactone or lactide reactant to form the biodegradable and hydrodegradable diblock copolymer.

International Classification:

A23D 902

US Classification:

4263306

Abstract:

A method of producing unsaponifiable rich refined vegetable oils by refining crude vegetable oils with a weak acid salt, e. g. , a carbonate salt, to produce a refined vegetable oil and a soapstock is described. The refined oil can be further refined with a strong base to produce unsaponifiable rich concentrates.

Assignee:

University of Massachusetts at Lowell - Lowell MA

International Classification:

C07K 710

US Classification:

530350

Abstract:

A method is disclosed for significantly diminishing the rate of degradation of naturally-produced. gamma. -PGA in a. gamma. -PGA-producing cell culture. Also, a method is disclosed for significantly decreasing the water solubility coefficient of naturally-produced. gamma. -PGA by forming derivatives of. gamma. -PGA. In addition, a polymer solution is disclosed which includes a polysaccharide component and a. gamma. -PGA component.

International Classification:

C08G 6308

US Classification:

528354

Abstract:

High molecular weight, biodegradable polymers of substituted-poly(. beta. -propioesters), wherein the repeat unit sequences have a predominantly syndiotactic arrangement and a method of forming such polymers are disclosed. The method includes exposing a substituted-. beta. -propiolactone to a tin-based organometallic catalyst for a sufficient combination of time and temperature to form the predominantly syndiotactic substituted-poly(. beta. -propioester).
