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, ...
Comment on "Observation of mutual diffusion of macromolecules in PS/PMMA binary films by confocal Raman microscopy"
(Royal Society of Chemistry, 2016-04-25)
A paper by Hu et al. (Soft Matter, 2012, 8, 4780) reports on the use of confocal Raman microscopy to resolve mutual diffusion between polystyrene (PS) and poly(methyl methacrylate) (PMMA). In-depth optical sectioning is ...
Intraocular Light Scatter in Eyes with the Boston Type 1 Keratoprosthesis
(Lippincott Williams, 2019-01)
Purpose: The Boston keratoprosthesis (KPro) is the most commonly used artificial cornea. It has been proven to be successful for severe corneal disease not amenable to keratoplasty. We have observed our patients reporting ...
Comparison of morphologies and mechanical properties of crosslinked epoxies modified by polystyrene and poly(methyl methacrylate)) or by the corresponding block copolymer polystyrene-b-poly(methyl methacrylate)
(Elsevier, 2005-03)
Polystyrene (PS, Mn=28,400, PI=1.07), poly(methyl methacrylate) (PMMA, Mn=88,600, PI=1.03), and PS (50,000)-b-PMMA (54,000) (PI=1.04), were used as modifiers of an epoxy formulation based on diglycidyl ether of bisphenol ...
PVDF/PMMA membranes for lemon juice clarification: fouling analysis
(Desalination Publ, 2015-07)
Microfiltration/ultrafiltration membranes with different degrees of hydrophilicity and structural characteristics from poly(vinylidene fluoride) (PVDF), polymethylmetacrylate (PMMA), and polyvinylpirrolidone (PVP) in ...
Composites from PMMA modified thermosets and chemically treated woodflour
(John Wiley & Sons Inc, 2003-04-07)
The mechanical behavior of composites made from woodflour and a modified thermoset unsaturated polyester resin has been examined. Polymethylmethacrylate (PMMA), a common low profile additive (LPA), was used as the matrix ...
Pd and Pd,In nanoparticles supported on polymer fibres as catalysts for the nitrate and nitrite reduction in aqueous media
(Elsevier Ltd, 2019-12)
The presence of high concentrations of nitrate and nitrite ions in water sources is an actual environmental problem. Nowadays, there are several technologies for nitrate and nitrite treatment, but most of them involve the ...
Double phase separation induced by polymerization in ternary blends of epoxies with polystyrene and poly(methyl methacrylate)
(American Chemical Society, 2001-04)
Ternary blends based on a stoichiometric mixture of diglycidyl ether of bisphenol A (DGEBA) and 4,4'-diaminodiphenyl sulfone (DDS), monodisperse polystyrene (PS, 8.3 × 104 g/mol), and monodisperse poly(methyl methacrylate) ...
