Kato, Makoto; Toshima, Kazunobu; Matsumura, Shuichi published the artcile< Direct Enzymatic Synthesis of a Polyester with Free Pendant Mercapto Groups>, Recommanded Product: (S)-Dimethyl 2-hydroxysuccinate, the main research area is hexanediol dimethyl mercaptosuccinate enzymic polymerization polyester preparation property; stereochem monomer effect enzymic polym dimethylmercaptosuccinate.
An aliphatic polyester with free pendant mercapto groups was prepared by direct lipase-catalyzed polycondensation of hexane-1,6-diol and di-Me 2-mercaptosuccinate. The polycondensation reaction using immobilized lipase from Candida antarctica (lipase CA) was carried out in bulk at 70 °C without any formation of disulfide or thioester linkages to produce the corresponding polyester with Mw = 14000 g/mol in high yield. The content of free mercapto groups in the polyester could be controlled by copolymerization with other monomers. The obtained polyester was easily crosslinked to form gels by the air oxidation of the pendant thiols to disulfides in DMSO. The effect of stereochem. of the monomers was studied.
Biomacromolecules published new progress about Crosslinking. 617-55-0 belongs to class esters-buliding-blocks, and the molecular formula is C6H10O5, Recommanded Product: (S)-Dimethyl 2-hydroxysuccinate.
