Nonoxidative thermal degradation kinetic of polyamide 6,6 reinforced with carbon nanotubes
(Sage Publications Ltd, 2013-11-01)
The thermal degradation of the polyamide 6,6 (abbreviated henceforth as PA 6,6) reinforced with different concentrations of carbon nanotubes (CNTs) was investigated by means of thermal analysis. In this study, the ...
Kinetic parameters obtained for thermal decomposition of acrylic resins present in commercial paint emulsions
(Springer, 2007-06-01)
Samples of water based commercial acrylic resin paints were spread in a film form on slides, dried at room temperature and exposed to solar radiation for up to eight months.The characterization and quantification of resins ...
Modeling a system of phosphated cross-linked high amylose for controlled drug release. Part 1: Synthesis and polymer characterization
(Elsevier B.V., 2008-08-01)
High amylose was cross-linked with sodium trimetaphosphate (STMP) using 2% and 4% solutions of NaOH at room temperature with reaction contact times of 0.5, 1, 2 and 4 h. The different polymers obtained were analyzed by FT ...

Kinetic studies of the polymerization of an epoxy resin modified with rhodamine B
(Elsevier, 2009-09)
Novel fluorescent materials were satisfactorily synthesized. With this aim, an epoxy resin based on diglycidyl ether of bisphenol A (DGEBA) was reacted with a laser dye, rhodamine B (RB), to achieve an epoxy-based prepolymer. ...
Curing kinetics of a furan resin and its nanocomposites
(Elsevier Science, 2011-03)
A furan resin was synthesized from furfural and phenol and it was expected to have similar properties to the commonly used phenolic resins because the former was obtained by the replacement of formaldehyde by furfural, ...
Tin(II)-EDTA complex: kinetic of thermal decomposition by non-isothermal procedures

Immobilization of pectinmethylesterase from acerola (Malpighia glabra L.) in porous silica
(Kluwer Academic Publ, 2003-06-01)
The total and partially purified enzyme pectinmethylesterase from acerola fruit was covalently immobilized on porous silica particles. These efficiency values were 114% for the total PME and 351% for the partially purified ...
Screening of supports for the immobilization of pectinmethylesterase from acerola (Malpighia glabra L)
(Wiley-Blackwell, 2004-03-01)
A partially purified extract of pectinmethylesterase (PME) from acerola fruit was immobilized on various supports: glass, celite, chrysotile, agarose, concanavalin A Sepharose 4B, egg shell, polyacrylamide and gelatin. In ...
