Morphological raman analysis of short chain branched ethylene and propylene metallocenic copolymers
(Elsevier, 2018-05)
Spectroscopic features in the Raman spectra of semicrystalline polyolefins that characterize different phase morphologies are reported. With growing incorporation of different 1-olefins, changes in the spectra due to ...
Synthesis of Grafted Block Copolymers Based on e-Caprolactone: Influence of Branches on Their Thermal Behavior
(Wiley Vch Verlag, 2015-11-17)
Branched copolymers are a special class of polymeric materials in which are refl ected the combined effects of polymer segments and architectural constraints of the branched architecture. This study employed two methodologies ...

Effects of Branches on the Isothermal Crystallization of Copolymers Based on Poly(ϵ-caprolactone)
(Wiley, 2019-02)
A linear poly(ϵ-caprolactone), PCL, and grafted copolymers based on poly(2-hydroxyethylmethacrylate) and poly(ϵ-caprolactone) are used to study the effect of branches on PCL crystallization process. Copolymers are synthetized ...
Branching and rheological behavior after electron irradiation in metallocene ethylene-co-norbornene copolymers
(Elsevier, 2011-02)
The effect of Electron beam (EB) irradiation on a cycloolefin copolymer based on ethylene and norbornene with intermediate molar content of norbornene has been evaluated. Crosslinking is not observed at any dose analyzed. ...
STUDY OF THE EFFECT OF BRANCHING IN DEGRADATION OF POLYETHYLENES OBTAINED VIA METALLOCENE CATALYST

Composite coatings based on linear and branched block copolymers for hydroxyapatite deposition in simulated body-fluid
(Taylor & Francis, 2020-01)
In this work, the fabrication of composite coatings based on block copolymers and silicates deposited on stainless-steel plates through electrophoretic deposition technique was studied. Linear poly(ɛ-caprolactone), and ...
