Avaliação da degradação de poliamida 11 empregada em cabos umbilicais por viscosidade inerente e reometria em regime oscilatório
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação de Mestrado Profissional em Química - PPGQCâmpus São Carlos, 2020-07-29)
Umbilical cable is one of the main systems for monitoring, powering, and supplying chemicals foroffshore oil and gas wells. Polyamide 11 (PA 11) composes the ducts for the chemical injection andcan suffer ...
Interaction of the nonionic surfactant C12E8 with high molar mass poly(ethylene oxide) studied by dynamic light scattering and fluorescence quenching methods
(1996-12-11)
Dynamic light scattering has been used to investigate ternary aqueous solutions of n-dodecyl octaoxyethylene glycol monoetber (C12E8) with high molar mass poly(ethylene oxide) (PEO). The measurements were made at 20 °C, ...

Cagelike precursors of high-molar-mass silsesquioxanes formed by the hydrolytic condensation of trialkoxysilanes
(American Chemical Society, 2000-03-01)
High-molar-mass silsesquioxanes (SSQO) based on (3-glycidoxypropyl)trimethoxysilane (GPMS) and (3-methacryloxypropyl)trimethoxysilane (MPMS) were synthesized. The hydrolytic condensation of GPMS was performed using HCOOH ...
Polimerização catiônica em solução e miniemulsão mediada por líquidos iônicos imidazólicos
(2018)
Líquidos iônicos (LIs) são muito atraentes para uma série de aplicações, porém ainda pouco explorados como iniciadores de reações de polimerização. O objetivo principal deste trabalho é avaliar o potencial de líquidos ...

Mass fractal characteristics of silica sonogels as determined by small-angle x-ray scattering and nitrogen adsorption
(American Physical Soc, 2005-01-01)
A sample series of silica sonogels was prepared using different water-tetraethoxysilane molar ratio (r(w)) in the gelation step of the process in order to obtain aerogels with different bulk densities after the supercritical ...
