  ADMET Synthesis of Polyolefins Targeted for Biological Applications

  摘要：

  A series of "N-terminus" amino acid and peptide branched, chiral polyolefins, termed bioolefins, have been prepared using acyclic diene metathesis (ADMET) polycondensation chemistry, using a minimal amount of solvent and Grubbs' second generation catalyst. The carboxylic acid functional groups were protected with methyl, benzyl, and tert-butyl esters to enhance both the polymerizability of the monomers themselves and the solubility of the resulting polymers. A number of these polymers are semicrystalline, exhibiting melt transitions of up to 132 and 74 degreesC for the amino acid and dipeptide branched polymers, respectively. Adding a succinic acid spacer between the amino acid entity and the polymer backbone alters the melting behavior of the polymer, increasing the peak melting point by 27 degreesC when compared to a polymer having the same amino acid directly attached to the polymer backbone.

  has a pronounced effect on processability and drawability. Regularly branched model polyolefins were studied by advanced solid‐state NMR spectroscopy, and twist defects around the branches in the crystalline regions are identified. For lower branch content, the twisting motions are decoupled; for higher content, collective motion is found (see picture).

  分支：线性聚合物的迁移率在分支时发生变化，这对可加工性和可拉伸性具有显着影响。通过先进的固态NMR光谱研究了规则支化的模型聚烯烃，并鉴定了结晶区域分支周围的扭曲缺陷。对于较低的分支含量，扭转运动是解耦的。对于更高的内容，可以找到集体运动（参见图片）。

  The present invention is related to a linear functional polymer having repeating units A, B and D. Unit A represents —CH 2 —, unit B represents and unit D represents where R 1 represents a polar functional group. There are at least four A units separating each B unit, each D unit, and each B and D unit. The value y represents the total number of B units and is an integer greater than or equal to 1. The total number of D units is represented by h and is an integer greater than or equal to 0. And x represents the total number of A units and is an integer sufficient that the molar fraction of the B and D units in the linear functional polymer is represented by a value j defined by the equation: j = y + h x + y + h ≤ 0.032 . The present invention is also directed to a method for preparing such linear functional polymers by copolymerizing a first polar substituted monomer and a second non-polar unsubstituted monomer.

  A method of preparing periodic, semi-periodic, or semi-random polyethylene-co-acrylic acid or polyethylene-co-methacrylic acid involves polymerizing 1-alkoxyalkyl ester substituted α,Ω-dienes, and/or 1-alkoxyalkyl ester substituted cycloalkenes via olefin metathesis reactions followed by hydrogenation of the alkylene units and subsequently hydrolyzed to the desired polyethylene-co-acrylic acid or polyethylene-co-methacrylic acid. The polyethylene-co-acrylic acid or polyethylene-co-methacrylic acid can then be converted to ionomers by exchange with a monomeric carboxylate salt.
