| titleOfInvention | Poly(alkylene carbonate-delta-valerolactone) copolymer and method of preparing same |
| abstract | FIELD OF THE INVENTION The present invention relates to poly (alkylene carbonate-delta-valerolactone) copolymers and processes for the preparation thereof, which process comprises tertiary copolymerization of carbon dioxide, alkylene oxide and delta-valerolactone under a catalyst. . The poly (alkylene carbonate-delta-valerolactone) copolymer prepared by this preparation method has the following formula (1).n n n [Formula 1]n n n n n n n n (Wherein -OA- is ethylene oxide, propylene oxide, 1-butene oxide, 1,1-dimethylethylene oxide, cyclopentene oxide, cyclohexene oxide, 1-phenylethylene oxide, 1-vinylethylene oxide and 1- Alkylene oxides selected from the group consisting of trifluoromethylethylene oxide ( Ring-open chemical structure ofn n n x and y are each an integer of 2,000 or less irrespective of each other, n is an integer with n and (x-x-y) in relation to x and y, where z is an integer of 20,000 or less.)n n n As described above, the present invention, as described above, the present invention can produce a biodegradable poly (alkylene carbonate-delta-valerolactone) copolymer using carbon dioxide which is the main cause of air pollution. In addition, the poly (alkylene carbonate-delta-valerolactone) of the present invention is a copolymer exhibiting excellent hydrolysis and biodegradation properties, and is expected to be applied and utilized as a general-purpose polymer material as well as a medical polymer material. |
