The molecular mass of two sodium alginates with the same composition but different chain length is reduced via a simple ultrasonic treatment and monitored by rheological measurements. The polymer molecular mass decreases until a lower limiting value of 100 kg/mol is reached, with the degradation occurring via a mid-pointchain kinetic consisting...

Nel presente lavoro è stata investigata la natura polielettrolitica in soluzione acquosa di tre biopolimeri (sodio alginato, chitosano e acido ialuronico). Al fine di ottenere informazioni sui diversi regimi di concentrazione, i fattori di scala della viscosità specifica sono stati utilizzati per determinare le concentrazioni critiche (c*, ce e...

Mark–Houwink parameters are determined for sodium alginate with low (SA LV) and medium (SA MV) molecular mass via a rheological approach. Firstly, salt screening concentration and polyelectrolyte nature of the polymers are investigated. Despite both alginates behaving as neutral polymer in θ solvent, differences are observed between them with...

The aim of the present study was the assessment of a methodological approach to evaluate the degree of curing of epoxy resins heavily loaded with fillers, used as fairing compounds in coating systems applied to protect the hull of yachts and ships with the aim of filling superficial imperfections. The evaluation of the curing process was...

Epoxy resins, heavily loaded with fillers, are used as fairing compounds in coating systems to fill superficial imperfections and protect the hull of yachts and ships; they are complex composite materials whose final performance can be heavily affected by the conditions of application. In this paper the curing process of an...
