产品介绍：β-丁内酯在乙氧基桥连双核铟催化剂存在下进行开环聚合，得到可生物降解的聚酯聚羟基丁酸酯。外消旋手性引发剂存在下的β-丁内酯聚合已有报道。它是有机合成的通用构件。β-Butyrolactone undergoes ring opening polymerization in the presence of ethoxy-bridged dinuclear indium catalyst to yield biodegradable polyester poly(hydroxybutyrate). Polymerization of racemic β-butyrolactone in the presence of chiral initiators has been reported. It is versatile building block for organic synthesis.β-Butyrolactone was used in the preparation of (3-O-[oligo-(3-hydroxybutyrate ester)] fluorescein, fluorescein derivative of poly(3-hydroxybutyrate) via anionic polymerization。β-Butyrolactone undergoes ring opening polymerization in the presence of ethoxy-bridged dinuclear indium catalyst to yield biodegradable polyester poly(hydroxybutyrate).
