Mechanism and molecular weight model for thermal oxidation of linear ethylene-butene copolymer
(Elsevier, 2001-12)
The mechanism of thermooxidative degradation at 80°C of a narrow distribution linear ethylene-butene copolymer has been described by determining the chemical modifications and molecular weight distribution changes occurring ...
Crystallization behavior of random ethylene-butene copolymers modified with organic peroxide
(Elsevier Science, 2012-01-02)
The effect of molecular cross-linking on the crystallization of random ethylene-1-butene copolymers obtained from hydrogenation of model polybutadiene was studied by means of differential scanning calorimetry. The copolymers ...
Effect of radiation-induced oxidative degradation on the non-isothermal crystallization of ethylene-butene copolymer
(Elsevier, 2019-12)
A random ethylene–butene copolymer was irradiated with high ionizing energy in environments with different oxygen concentration. The non-isothermal crystallization process of the materials was studied by differential ...
The use of SSA fractionation to detect changes in the molecular structure of model ethylene–butene copolymers modified by peroxide crosslinking
(Elsevier, 2009-07)
Four model ethylene–butene copolymers of different molecular weights modified with various concentrations of peroxide were analyzed by a DSC based successive self annealing method. The original copolymers had the same intra ...
Modification of model ethylene-butene copolymers using an organic peroxide
(Elsevier, 2005-01-26)
Well-characterized linear ethylene-butene-1 copolymers with polydispersities lower than 1.1 were modified using an organic peroxide with the purpose of assessing the relative importance of chain-linking processes. The ...
SSA study of early polyethylenes degradation stages. Effects of attack rate, of average branch length, and of backbone polymethylene sequences length distributions
(Elsevier, 2012-10-24)
Low-density polyethylenes have been attacked by free radicals in the presence of oxygen to promote chains scission, aiming at showing effects of the molecular structure on the thermal behavior as determined by using a ...
The effect of oxygen on the irradiation process of ethylene-butene copolymer
(Elsevier, 2012-08)
A model ethylene-butene copolymer of narrow molecular weight distribution was irradiated with γ-rays under different oxygen-containing atmospheres. Gel fraction, carbonyl content and molecular weights were measured. Weight ...
Grafting of diethyl maleate and maleic anhydride onto styrene-b-(ethylene-co-1-butene)-b-styrene triblock copolymer (SEBS)
(Elsevier Sci LtdOxfordInglaterra, 2000)
Elastomeric ethylene copolymers with carbon nanostructures having tailored strain sensor behavior and their interpretation based on the excluded volume theory
(2016)
Two ethylene/1-butene thermoplastic elastomer copolymers were melt mixed with either multiwalled carbon nanotubes (CNTs) or thermally reduced graphite oxide (TrGO) resulting in piezoresistive composite materials. The effect ...
Effect of montmorillonite on the crystallization and thermal degradation of poly(propylene-coethylene- co-1-butene) nanocomposites
(Sage Publications, 2016-07)
Polymeric nanocomposites based on poly(propylene-co-ethylene-co-1-butene) (PEBC) were elaborated by melt mixing using an organophilic montmorillonite (o-MMT) and maleated PEBC (PEBCg) as compatibilizer. The effect of clay ...
