Aminoxyl-Containing Radical Spin Labeling in Polymers and Copolymers
- Detailed Technology Description
- Aminoxyl-containing radical is provided in polymers and copolymers by replacing a hydroxyl moiety in a carboxyl group at a chain end of a starting material biodegradable polymer or copolymer with imino or oxy linked to aminoxyl-containing radical to form an amide linkage or an oxycarbonyl linkage at the chain end of biocompatible polymers or copolymers to the aminoxyl-containing radical.

- *Abstract
-
Aminoxyl-containing radical is provided in polymers and copolymers by replacing a hydroxyl moiety in a carboxyl group at a chain end of a starting material biodegradable polymer or copolymer with imino or oxy linked to aminoxyl-containing radical to form an amide linkage or an oxycarbonyl linkage at the chain end of biocompatible polymers or copolymers to the aminoxyl-containing radical. Preferred starting material polymers and copolymers are prepared from the hydroxy alkyl carboxylic acid monomers glycolic acid and lactic acid. Preferred aminoxyl-containing radical is 2,2,6,6-tetramethylpiperidine-1-oxy. Product polymers are useful for aminoxyl-containing radical treatment of tumors, and to increase the efficiency of chemotherapy and ionizing radiation therapy of tumors and for the reconstruction of injured, diseased, or aged human blood vessels.
