چکیده
Polymer matrix reinforced by woven fabrics is probably the most commonly used form of composites in structural application such as aircrafts, boats, and automobiles, etc. [1].The fiber reinforced polyurethane (PU) are being used for high performance composites due to their light weight and superior heat insulation as well as good mechanical characteristics. The high versatility of polyurethane allows to produce a large variety of products with structures which may range from liner and flexible to highly cross-linked and rigid, and capable of satisfying various application requirements [2]. Since a large quantity of waste foams have been discharged in the various stages of manufacture, processing, and after usage, it is becoming necessary for them to be treated or recycled [3]. Glycolysis is a comparatively simple process in which diols are used to convert polyurethanes into a liquid

Well-defined PE-b-PTFE diblock copolymers via combination of coordination chain transfer polymerization and condensation reaction: Facile preparation and surface modification of polyethylene film
In this paper, a series of well-defined polyethylene-b-polytetrafluoroethylene diblock copolymers (PE–b– PTFEs) were prepared by a coupling reaction of hydroxyl-terminated polyethylene (PE–OH) and isocyanateterminated 1H,1H-perfluoro-1-tetradecanol (PFDO–NCO). PE–OH was prepared by the coordination chain transfer polymerization using 2,6-bis[1-(2,6-diisopropylphenyl)imino ethyl] pyridine iron (...

Exfoliated poly (Chloromethyl styrene-co-styrene)-g-polyacrylonitryle/organo- modified montmorillonite [P(CMSt-co-St)-g-PAN/O-MMT] nanocomposite was synthesized through solution intercalation method by using atom transfer and nitroxide mediated radical polymerization. At first, poly (chloromethyl styrene-costyrene) copolymer was synthesized by nitroxide - mediated “living” free radical polyme...
متن کاملPropene-cycloolefin polymerization
Highly active metallocenes and other single site catalysts have opened up the possibility of polymerizing cycloolefins such as norbornene (N) or of copolymerizing them with ethene (E) or propene (P). The polymers obtained show exciting structures and properties. E-N copolymers are industrially produced materials, with variable and high glass transitions depending on the wide range of their micr...

In this work, new biodegradable ABCBA type pentablock copolymers with different mole ratio of L-lactide and PPDO-b-PEG-b-PPDO triblock copolymer were synthesized and characterized. In the first step, PPDO-b-PEG-b-PPDO triblock copolymer was synthesized via a ring-opening polymerization of P-DiOxanone (PDO) monomer with Poly (Ethylene Glycol) (P...
متن کاملA Thermodynamic Study of the Interactions between Acetamide Derivatives and PCA-PEG-PCA Copolymers: ONIOM Calculations
To improve drug selectivity toward target cells, one interesting approach for drug delivery is to use polymer nanoparticles. A two-layered ONIOM Becke3- LYP: UFF calculation was carried out to study the structural and thermodynamic properties of the interaction between acetamide derivatives and the PCA-PEG-PCA copolymers. The Interaction enthalpies and the Gibbs free energies between acetamide ...
