摘要: The potential to fine-tune the transition temperatures of polymers displaying lower-critical solution (LCST) by a simple mixing strategy is investigated. Using panel four distinct polymer classes (poly[oligo(ethyleneglycol)methacrylate], poly(N-vinylpiperidone), poly(N-vinylcaprolactam) poly(N-isopropylacrylamide)) it was shown that only those with strong molecular weight dependent LCSTs produced single, cooperative, when blended together. Furthermore, actual temperature linked average not number weight. which did show molecular-weight-LCST correlation poly(oligo(ethyleneglycol)methacrylate), showed two independent transitions, one for each polymer.
