Morphology and properties evolution upon ring-opening polymerization during extrusion of cyclic butylene terephthalate and graphene-related-materials into thermally conductive nanocomposites [PDF]

open access: yes, 2017
In this work, the study of thermal conductivity before and after in-situ ring-opening polymerization of cyclic butylene terephthalate into poly (butylene terephthalate) in presence of graphene-related materials (GRM) is addressed, to gain insight in the ...

On consistent gauge fixing conditions in polymerized gravitational systems [PDF]

open access: yesPhys. Rev. D 105, 066023 2022, 2021
For classical gravitational systems the lapse function and the shift vector are usually determined by imposing appropriate gauge fixing conditions and then demanding their preservation with respect to the dynamics generated by a canonical Hamiltonian.

Polymerization Reactions and Modifications of Polymers by Ionizing Radiation

open access: yesPolymers, 2020
Ionizing radiation has become the most effective way to modify natural and synthetic polymers through crosslinking, degradation, and graft polymerization. This review will include an in-depth analysis of radiation chemistry mechanisms and the kinetics of

Polyethers for biomedical applications. Polymerization of propylene oxide by organozinc/organotin catalysts [PDF]

open access: yes, 1987
The polymerization of propylene oxide to obtain a high-molecular-weight polymer with an atactic structure required for the application as artificial blood vessels was investigated using combinations of organozinc and organotin compounds as catalyst.

The Shape of the Polymerization Rate in the Prion Equation [PDF]

open access: yesMathematical and Computer Modelling, 2011, 53 (7-8), pp.1451-1456, 2010
We consider a polymerization (fragmentation) model with size-dependent parameters involved in prion proliferation. Using power laws for the different rates of this model, we recover the shape of the polymerization rate using experimental data. The technique used is inspired from an article of Zampieri et al.
