The thermoreversible gel formation of syndiotactic polystyrene (SPS) was studied in detail. Even if SPS solutions with high concentrations did not form gels, there were the cases where SPS formed gels at lower concentrations of SPS, which favor the f

We dissolved low concentration of syndiotactic polystyrene (SPS) in serial n-alkylbenzenes (NB: C 6 H 5 –C N H 2N+1 ( N = 1–10)) at high temperatures and observed the morphology and structure after cooling by SEM, IR, DSC, and WAXD. The morpholog

Summary: Gelation of syndiotactic poly(p-tert-butylstyrene) (sPTBS), a syndiotactic polystyrene (sPS) derivative having a larger side-chain group, was first examined with several solvents. The temperature-concentration phase diagram of sPTBS/trans-de
