Polymerization kinetics of oligoesteracrylates at high degrees of conversion
Polymer Science U.S.S.R., 1967IF [1, 2] IT was reported tha t the polymerization kinetics of oligoesteracrylates t (OEA) is a diffusion-controlled process even at low degrees of conversion (G< 1%). At these G the influence of the physical properties (viscosity) of the reaction system on the apparent reactivity of OEA consists mainly in the recombination of polymer radicals, the ...

Degree of Conversion of Dehydroxylation in a Large Electroceramic Body
International Journal of Thermophysics, 2010The initial composition (36 mass% kaolin, 30 mass% alumina, 22 mass% feldspar, 12 mass% clay) and density of a body containing kaolinite is substantially altered during dehydroxylation which starts at a temperature of ~420 °C. Values of the degree of the dehydroxylation conversion of kaolinite into metakaolinite were experimentally obtained from a ...

Degree of conversion and Knoop microhardness of a silorane composite
Dental Materials, 2014Purpose: To evaluate the relationship between degree of conversion and microhardness of a composite based on silorane monomers (Filtek P90-3M ESPE). Methods andmaterials: The specimens (n=10/gp, cylindrical 5mm× 2mm, light-cured 1100mW/cm2) were divided into 5 groups according to the energy amount obtained by the variation in the irradiation time (8 ...

Reducing the degrees of freedom in chemistry classroom conversations
Chem. Educ. Res. Pract., 2012Five high-school chemistry teachers were asked to enact a lesson in which they posed a problem for which students were likely to generate solutions based on reasoning that was not aligned with accepted principles of chemistry. Four teachers selected a problem related to the stoichiometry of a reaction; the fifth chose a problem associated with periodic

Hardness and degree of conversion of posterior packable composites.
Operative dentistry, 2005Knoop microhardness and the degree of conversion of three packable composites (SureFil, Alert and Solitaire), a microfil composite (Heliomolar), a microhybrid composite (Herculite) and an indirect laboratory-processed composite (Belleglass) were evaluated as a function of distance from the irradiated surface.
