Linear viscoelastic behavior of compatibilized PMMA/PP blends
(2013)
In this work, the morphology and linear viscoelastic behavior of PMMA/PP blends to which a graft copolymer PP-g-PMMA has been added was studied. The copolymer concentration varied from 1 to 10 wt % relative to the dispersed ...
Análisis cuantitativo de Streptococcus mutans y Candida albicans en resinas compuestas para uso en bases protésicas (estudio in vitro)
(UNIVERSIDAD AUTONOMA DEL ESTADO DE MEXICO, 2022)
Influence of the Addition of Polystyrene-blockpoly(methyl methacrylate) Copolymer (PS-b-PMMA) on the Morphologies Generated by Reaction-Induced Phase Separation in PS/PMMA/Epoxy Blends
(Wiley VCH Verlag, 2002-04-11)
Homogeneous solutions of polystyrene (PS) and poly(methyl methacrylate) (PMMA) in diglycidylether of bisphenol A, containing about 8 wt.‐% total thermoplastic, and with or without 0.5 wt.‐% of a PS‐b‐PMMA block copolymer, ...
Desenvolvimento de híbridos PMMA-(TiO2, ZrO2 e CeO2) multifuncionais
(Universidade Estadual Paulista (Unesp), 2019-04-25)
Híbridos orgânico-inorgânicos constituídos de poli(metacrilato de metila) (PMMA) covalentemente ligado a diferentes fases inorgânicas (TiO2, ZrO2 e CeO2) foram sintetizados pelo processo sol-gel com objetivo de obter ...
Effect of sample pre-cracking method and notch geometry in plane strain fracture toughness tests as applied to a PMMA resin
(ELSEVIER SCI LTDOXFORD, 2012)
The influence of test method factors (notch shape, square or angular, and pre-cracking method, by tapping onto or pressing a razor blade) on the results obtained in plane strain fracture toughness test according to standard ...
Stress relaxation behavior of PMMA/PS polymer blends
(SPRINGER, 2009)
In this work, the stress relaxation behavior of PMMA/PS blends, with or without random copolymer addition, submitted to step shear strain experiments in the linear and nonlinear regime was studied. The effect of blend ...
The role of polymeric nanofibers on the mechanical behavior of polymethyl methacrylate resin
(2020-12-01)
This study aimed to synthesize and characterize non-woven acrylonitrile butadiene styrene (ABS), polyamide-6 (P6), and polystyrene (PS) nanofibers, and evaluate their effects on the flexural strength and fracture resistance ...
Estrutura e propriedades térmicas de nanocompósitos PMMA-argilas contendo ferro
(Universidade Estadual Paulista (Unesp), 2021-10-11)
Os nanocompósitos polímero-argila apresentam melhores propriedades térmicas e de retardamento de chama em comparação com a matriz polimérica. A barreira física induzida pela argila e o aprisionamento de radicais livres ...
