functionalized acrylate derivatives with the view to prepare functional polymers was explored. Hard zincalkoxide generation enabled the highly chemoselective transesterification of acrylate derivatives over the undesired conjugate addition, which caused polymerization. The combined use of the catalytic zinc cluster Zn4(OCOCF3)6O and 4-(dimethylamino)pyridine delivered various functionalized acrylate derivatives

A method of stabilizing a color image resulting from the photomodulation of a Christiansen cell is provided by adding a cross-linking monomer to an optically homogeneous, photopolymerizable medium of a Christiansen cell in an amount sufficient to produce cross-linked polymer upon exposure to actinic light which stabilizes the color image formed and maintains the optical homogeneity of the medium. An improved color image can be formed by also adding to the medium a small amount of a nitroso dimer.
We synthesized a new family of chemicallyrecyclable polymers in a large scale from the sustainable monomers H2O, COS, and diacrylates. Such resultant polymers manifest impressive toughness and ductility comparable to commodity polyethylene. The chemicalrecycling of these polymers can be readily achieved through two closed loops.
我们从可持续单体 H 2 O、COS 和二丙烯酸酯中大规模合成了一系列新的化学可回收聚合物。此类所得聚合物表现出与商品聚乙烯相当的令人印象深刻的韧性和延展性。这些聚合物的化学回收可以很容易地通过两个闭环实现。
