  • Soluble Hyperbranched Poly(glycolide) Copolymers
    作者:Anna M. Fischer、Holger Frey
    DOI:10.1021/ma101710t
    日期:2010.10.26
    measurements showed that in contrast to linear PGA (Tm > 220 °C) the melting behavior and the glass-transition temperature of the branched poly(glycolide) copolymers changed drastically. The presence of dendritic units in the polymer backbone resulted in a depression of the melting point and amorphous materials at amounts of BHB exceeding 15%. The amorphous hyperbranched poly(glycolide) copolymers show enhanced
    通过乙交酯(GA)与2,2-双(羟甲基)丁酸(BHB)经由ROP / AB 2-缩聚反应共聚制备了一系列(超)支化聚(乙交酯)共聚物。本体聚合反应并通过己二酸-2-乙基(Sn(Oct)2)催化。通过1D和2D-NMR光谱对所得聚酯的支链拓扑进行了详细研究,并通过模型化合物的合成和表征得到了证实。AB 2单体BHB以树状或焦点单元的形式引入,但几乎不以线性或末端模式引入。如多功能缩聚所预期的那样,SEC测量显示多分散指数范围为1.88至3.40的多分散产物。中号ñ共聚物的重量在1100至4000g / mol之间变化。MALDI-TOF MS分析可以验证主要的聚合物种类。此外,MALDI-TOF证明每个大分子结合了多个BHB单元,证实了成功的缩合反应和支化共聚物的形成。详细的1 H NMR表征(1D和2D方法)允许计算摩尔组成,转化率和支化度(DB),范围在0.12和0.44之间。差示扫描

  • Lipase Catalysis. A Direct Route to Linear Aliphatic Copolyesters of Bis(hydroxymethyl)butyric Acid with Pendant Carboxylic Acid Groups
    作者:Ankur S. Kulshrestha、Bishwabhusan Sahoo、Wei Gao、Hongyong Fu、Richard A. Gross
    DOI:10.1021/ma0480291
    日期:2005.4.1
    Immobilized Lipase B from Candida antartica (CAL-B, Novozyme 435) catalyzed terpolymerizations of bis(hydroxymethyl)butyric acid, BHB (AB(2)) and 1,8-octanediol (B-2) with adipic acid (A(2)). The copolymerizations of these AB(2), B-2, and A(2) monomers were conducted in bulk, at 80 degrees C, without activation of the acid groups. Carbon (C-13) NMR studies using a series of model BHB derivatives showed that CAL-B was strictly selective for esterification of BHB hydroxyl groups while leaving the carboxylic acid unchanged. Thus, all polymerizations were conducted as if BHB were a B2 monomer and then formulating a 1 to 1 ratio of carboxylic acid to hydroxyl groups in the monomer feed. By varying the monomer feed ratio, copolyesters with 9-45 mol % BHB-adipate units were formed with M-w values between 21900 and 2300 g/mol. By this direct polymerization without protection - deprotection chemistry, a series of linear aliphatic copolyesters with controlled quantities of pendant free acid groups was prepared. Thermal and crystalline properties of the copolyesters were studied by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and wide-angle X-ray scattering (WAXS). Increasing the BHB content in the copolyesters resulted in melting temperature depressions that were well described by Baur's equation for random copolymers where BHB-adipate units are excluded from the crystal phase of the crystallizable 1,8-octanediol-adipate units.
