study of ethylene/vinyl acetate transformation to ethylene/vinyl alcohol copolymer by nmr and dsc
hydrolysis of ethylene-vinyl acetate copolymer in alkaline conditions using two systems of naoh/methanol and koh/isopropanol has been studied and the formation of ethylene-vinyl alcohol copolymer was systematically examined using nmr spectroscopy and dsc measurements. vinyl acetate weight percentage and the degree of hydrolysis were calculated from nmr spectroscopy and it is shown that hydrolys...

متن کاملMiniemulsion Copolymerization of Ethylene and Vinyl Acetate
The copolymerizations of a gaseous monomer (ethylene) and a liquid monomer (vinyl acetate) via emulsion and miniemulsion polymerizations are reported. Reactions in which the vinyl acetate was introduced in both batch and semibatch modes are carried out. (Ethylene introduction is always in a semibatch model since the polymerization is carried out under a constant pressure of ethylene in the reac...
متن کاملMechanical behavior of ethylene vinyl acetate copolymer (EVA) used for fabrication of mouthguards and interocclusal splints.
In the present investigation, an experimental dental arch model fabricated in epoxy was assayed in Kratos universal testing machine to study the mechanical behavior of ethylene and vinyl acetate copolymer (EVA) in the form of mouthguard for sports and flat plate. The following variables were considered: thickness (3 and 4-mm plates), temperature (room and mouth temperature) and presence/absence...
متن کاملInter- and Intrachain Associations of an Ethylene-Vinyl Acetate Random Copolymer in Dilute 1,2-Dichloroethane Solutions
Laser light scattering (LLS) has been used to study an ethylene-vinyl acetate (EVA) random copolymer in 1,2-dichloroethane. The EVA solution was treated using two different thermal processes: (1) quickly quenching from 70 °C to 0 °C; and (2) slowly cooling from 70 °C to room temperature and annealing at room temperature for 24 h before further quenching to 0 °C. The LLS results reveal the forma...
