Abstract: Unlike low-molecular-weight inorganic or organic nucleating agents (NAs), the physical properties, including phase transition and rheological behaviors, of polymeric NAs are greatly influenced by molecular weight. In this paper, the molecular-weight dependence of the β-nucleation… read more here.

DOI: 10.1021/acs.macromol.8b01292
Abstract: Gelation of aqueous methylcellulose (MC) solutions upon heating has been shown to result from the formation of a network of semiflexible fibrils, with diameters of 15 ± 2 nm. Here, we investigate the impact of… read more here.

DOI: 10.1122/1.4984759
Abstract: Theoretical models regarding the slip of polymer melts are compared with the experimental results of several researchers on the basis of the molecular weight (Mw) dependence of the slip velocity (Vs). Using simple assumptions, it… read more here.
