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 ...
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 ...
Tailor-made, linear, and “comb-like” polyester-based copolymers: Synthesis, characterization, and thermal behavior of potential 3D-printing/electrospinning candidates
(Hindawi Publishing Corporation, 2018-10)
Tailor-made, linear, and “comb-like” poly(ε-caprolactone)-based copolymers were synthesized by employing a combination of controlled polymerization techniques. Poly(dimethylsiloxane-block-ε-caprolactone) copolymers (SCL#) ...
Poloxamine-based nanomaterials for drug delivery
(Frontiers In Bioscience Inc, 2010-12)
Poloxamines (Tetronic) are X-shaped amphiphilic block copolymers formed by four arms of poly(ethylene oxide)-poly(propylene oxide) (PEO-PPO) blocks bonded to a central ethylenediamine moiety. Such a structure confers ...
Effect of the molecular structure on the reactivity in a family of tetra-amine compounds derived from jeffamines
(Polymer Soc Korea, 2012-08)
The effect of the molecular structure on the reactivity of four first-generation linear-dendritic block copolymers derived from Jeffamines and bearing amine end groups is presented and discussed. Different parameters were ...
Inhibition of P-glycoprotein pumps by PEO–PPO amphiphiles: branched versus linear derivatives
(Future Medicine, 2010-12)
Inhibition of the activity of efflux transporters may relevantly improve the chemotherapy of cancer and infectious diseases. Aim: To explore the ability of poloxamines (Tetronic®, X-shaped structure with a central ...
Downregulation of mdr1 and abcg2 genes is a mechanism of inhibition of efflux pumps mediated by polymeric amphiphiles
(Pergamon-Elsevier Science Ltd, 2012-11)
The ability of cells to acquire resistance to multiple pharmaceuticals, namely multidrug resistance (MDR), is often mediated by the over-expression of efflux transporters of the ATP-binding cassette (ABC) superfamily; e.g., ...
Lactosylated poly(ethylene oxide)–poly(propylene oxide) block copolymers for potential active targeting: synthesis and physicochemical and self-aggregation characterization
(Springer, 2013-01-12)
Aiming to develop polymeric self-assembly nanocarriers with potential applications in active drug targeting to the liver, linear and branched poly(ethylene oxide)- poly(propylene oxide) (PEO-PPO) amphiphiles were conjugated ...
