Manual preparation of polymer samples for molecular weight characterization by solution methods such as gel permeation chromatography (GPC) is a timeconsuming, labor-intensive, and redundant task. Preparation of samples for high-temperature GPC characterization further complicates the procedure. A t
## Abstract The hydrolytic behaviors of polyphenylβ1,2,4βtriazine (AsβPPT) at high temperatures were investigated both experimentally and theoretically. The hydrolytic experiments of AsβPPT film and a reasonably designed model compound for the polymer were carried out in distilled water at 250Β°C/3.
