In situ interferometry was used to investigate the gelation process of polyacrylic acid (PAA) gels. The basicprinciple of the in situ interferometry technique i
Hyperbranched aromatic polymers were prepared by Friedel-Crafts reaction with Lewis acid, AlCl3 and ZnCl2, as the catalysts. In this work, hyperbranched polyben
