Claims (5)
- 有機グアニジン−無毒アルコールによりラクチドLA活性本体開環重合反応の触媒反応を行って生物可分解ポリ乳酸を合成するPLAプロセス。このプロセスは無毒の有機環状グアニジンカルボン酸塩RCOOCGを触媒として、無毒有機アルコールR’OHがイニシエータであり、本体重合法によりLAの活性開環重合反応を行う。
合成のステップ:
モノマーLA、触媒RCOOCG及びイニシエータR’OHを重合反応釜に入れる。その中、モノマーと触媒の初期モル比が[LA]0/[RCOOCG]0=1000〜1500:1であり、イニシエータR’OH初期モル投入量[R’OH]0が標的生成物PLA数平均分子量Mnの要求により下式により算出される。
式の中、
[LA]0:モノマーの初期モル投入量
モノマー、触媒及びイニシエータを反応釜に入れてから「真空作り−窒素充填」の操作を繰り返して重合釜にある空気を排出し、釜内圧力が1.0〜0.1torrに固定してから反応釜を密封し、30〜40分以内に95〜96 ℃になるまで撹拌し、96±1〜130±1℃で5〜300分に反応させる。 - 合成したPLA数平均分子量Mnは実際によりモノマーとイニシエータ初期モル比を調製して[LA]0/[R’OH]0、0.5×104〜5.0×104の範囲で合成でき、製品重合物分子量の分布指数PDIが1.10〜1.25、重合反応モノマー転化率が100%、色が真っ白であることを特徴とする請求項1に記載のプロセス。
- 前記のラクチドLAがL−ラクチドLLA、D−ラクチドDLA及びrac−ラクチドDLLA、ポリ乳酸PLAはポリ(L−乳酸)PLLA、ポリ(D−乳酸)PDLA、ポリ(D,L−乳酸)PDLLAを含むことを特徴とする請求項1または2に記載のプロセス。
- 前記の無毒有機アルコールイニシエータR’OHがエタノール(R’=−CH2CH3)またはラウリルアルコール(R’=−(CH2)11CH3)であってもよいことを特徴とする請求項1または2に記載のプロセス。
