摘要

我们研究了乐泰350®系列知名粘合剂的气体输运特性。在20 ~ 40℃范围内测定了氧、氮、二氧化碳和甲烷的渗透性、溶解度和扩散系数，以及扩散和渗透的活化能和溶液焓。Loctite 350®对O2/N2和CO2/CH4气体对具有较高的选择性和渗透性，特别是对O2/N2和CO2/CH4气体对。利用这些可光固化的聚合物在各种支撑物上制备非常薄的层的可能性使它们成为气体分离装置的有前途的材料。©2001 John Wiley & Sons, Inc[J] .高分子材料学报，2009,31 (3):786-795

Gas-transport properties in crosslinked polymers. I. Aliphatic polyurethane–acrylate-based adhesives

The gas-transport properties of one of a family of well-known adhesives, Loctite 350®, were studied. Permeability, solubility, and diffusivity coefficients, together with the activation energies of diffusion and permeation and the solution enthalpy, were determined from 20 to 40 °C for oxygen, nitrogen, carbon dioxide, and methane. Loctite 350® showed relatively high permselectivity and permeability for the gas pairs O2/N2 and CO2/CH4, especially for the former. The possibility of preparing very thin layers on various kinds of supports from these photocurable polymers makes them promising materials for gas-separation devices. © 2001 John Wiley & Sons, Inc.

期刊介绍： Since its launch in 1946 by P. M. Doty, H. Mark, and C.C. Price, the Journal of Polymer Science has provided a continuous forum for the dissemination of thoroughly peer-reviewed, fundamental, international research into the preparation and properties of macromolecules. From January 2020, the Journal of Polymer Science, Part A: Polymer Chemistry and Journal of Polymer Science, Part B: Polymer Physics will be published as one journal, the Journal of Polymer Science. The merged journal will reflect the nature of today''s polymer science research, with physics and chemistry of polymer systems at the heart of the scope. You can continue looking forward to an exciting mix of comprehensive reviews, visionary insights, high-impact communications, and full papers that represent the rapid multidisciplinary developments in polymer science. Our editorial team consists of a mix of well-known academic editors and full-time professional editors who ensure fast, professional peer review of your contribution. After publication, our team will work to ensure that your paper receives the recognition it deserves by your peers and the broader scientific community.
