Abstract
A monomeric diacid derivative includes at least two fatty acids coupled by a hydrolytically or enzymatically degradable bond. In a biological environment, the bond degrades forming naturally occurring fatty acid products thereby allowing elimination.
Claims12
A monomeric diacid derivative comprising between two and four fatty acids coupled by a hydrolytically or enzymatically degradable bond whereby said degradable bond degrades in a biological environment to form naturally occurring fatty acid products.
A method for synthesizing a biodegradable polymer containing hydrolyzable diacid fats comprising
- preparing a highly pure prepolymer of monomeric diacid derivative comprising between two and four fatty acids coupled by a hydrolytically or enzymatically degradable bond;
- polymerizing one highly pure prepolymer at a temperature and reaction time to form a polyanhydride or polyester of an appropriate molecular weight;
- and
- stopping said polymerization when the appropriate molecular weight product is obtained.
A plasticizing diacid derivative comprising between two and four fatty acids coupled by a hydrolytically or enzymatically degradable bond whereby said degradable bond degrades in a biological environment to form naturally occurring fatty acid products.
