Effect of annealing time on the self‐nucleation behavior of semicrystalline polymers
TL;DR: In this paper, the authors investigated the time dependence of the self-nucleation in Domain II self-melting and showed that if crystal fragments are present (even if undetected by the employed techniques) their final melting is a very slow process (in the order of hours).

TL;DR: In this paper, the influence of a pro-oxidant additive on the accelerated and environmental degradation of linear low density polyethylene (LLDPE) and LDPE was investigated.

TL;DR: The effectiveness of hydrophobically modified nanosilica (NS) as interfacial modifying agent for immiscible polymer blends is evaluated in this paper, where NS particles strongly reduce the polydispersity and droplet size of the dispersed phase, as a result of their preferential location at the interface.

Gelation kinetics of an imitation-mortadella emulsion during heat treatment determined by oscillatory rheometry
TL;DR: In this paper, the gelation kinetics of imitation-mortadella emulsion during thermal treatment under both, isothermal and non-isothermal conditions was followed by means of oscillatory rheometry.

Study of the adhesion strength on overmoulded plastic materials using the essential work of interfacial fracture (EWIF) concept
TL;DR: In this paper, the influence of the overmoulding processing conditions (melt and mould temperatures, holding pressure and injection rate) on the adhesion strength between two polymers in a hard-soft part was studied.
