“…Phenomenological softening points Were measured on 13 anionic atactic polystyrene samples using a DuPont 943 thermomechanical analyzer in a penetration mode (116). Dynamic mechanical techniques and DSC were used to study sulfonated polypentenamers containing 1.9-17.6 mol % pendant S03Na groups (183). A two-phase morphology was shown in segmented polyurethane, based on an OH-terminated butadiene rubber soft segment and containing 20-60% hard segments, by dynamic analysis and other techniques (23).…”

after 22 years of editing this review (160), has decided to turn the job over to another author. It is with a deep sense of responsibility and dedication that I hereby accept this challenge. The workers in the field of thermal analysis, as well as myself, should be eternally grateful to Dr. Murphy for his devoted and accurate reporting of thermal analysis activities as they occurred through the years. I only hope that I can continue this tradition in the manner and spirit that he did.As usual, this review covers the almost 2-year period from January 1980 through November 1981. Unfortunately, not all of the thermal analysis papers can be described here, due to their magnitude. An attempt has been made, however, to include representative studies in all of the thermal analysis areas as well as, in my judgement, new and novel ideas and developments. Due to space limitations, very few review articles (of which there are many), books, and meetings are included here.

Synthesis and characterization of carboxylated polysulfones

et al. 1990

View full text Add to dashboard Cite

Polysulfone has been carboxylated, via a metalated intermediate, by reaction of a THF solution of polymer with n‐butyllithium and then treatment with carbon dioxide. The polymer reactions with n‐butyllithium were close to quantitative and did not require the use of a tertiary amine catalyst. A series of polymers ranging from 0.2 to 1.9 carboxyl groups per repeat unit was prepared by this method in the salt, acid and ester form. The structures of these polymer derivatives were characterized by 1H‐NMR, 13C‐NMR and IR. The glass transition temperatures and thermal stabilities were characterized by differential scanning calorimetry (DSC) and thermogravimetry (TG).
