Thermoset-Thermoplastic Nanostructured Blends
(2015-09-23)
Polymers are chemical compounds of high molecular weight (on the order 1000-10,000.000), named macromolecule. They are formed by the repetition of a basic unit called mere whose parameter . n is defined by the degree of ...
Post‐Crosslinkable Blends: Reactions Between a Linear Poly(hydroxyl‐amino ether) and a Diepoxy
(Wiley VCH Verlag, 2004-11)
A thermoplastic poly(hydroxyl‐amino ether) polymer (BLOX) was blended with a diglycidyl ether of bisphenol A monomer (DGEBA). This system may be used as a crosslinkable thermoplastic. It means that it may be processed in ...
Free-radical polymerization induced macrophase separation in poly(methyl methacrylate)/dimethacrylate blends: experiment and modeling
(Pergamon-elsevier Science Ltd, 2013-09-13)
This work presents the analysis of a polymerization-induced macrophase separation taking place during free-radical copolymerization of styrene and dimethacrylate in the presence of poly(methyl methacrylate) (PMMA) as a ...
Poly(methyl methacrylate)-modified vinyl ester thermosets: Morphology, volume shrinkage, and mechanical properties
(John Wiley & Sons Inc, 2007-12)
Thermoset materials obtained from styrene/vinyl ester resins of different molecular weights modified with poly(methyl methacrylate) (PMMA) were prepared and studied. Scanning electron microscopy and transmission electron ...
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, ...
Thermodynamic Analysis of the Phase Separation during the Polymerization of a Thermoset System into a Thermoplastic Matrix. I. Effect of the Composition on the Cloud-Point Curves
(John Wiley & Sons Inc, 2004-04)
The cloud‐point curves of polystyrene (PS) mixed with reactive epoxy monomers based on diglycidyl ether of bisphenol A with stoichiometric amounts of 4,4′‐methylenebis(2,6‐diethylaniline) were experimentally studied. A ...
Thermodynamic analysis of the reaction-induced phase separation of solutions of random copolymers of methyl methacrylate and N, N-dimethylacrylamide in the precursors of a polythiourethane network
(John Wiley & Sons Inc, 2006-10)
Poly(methyl methacrylate) and random copolymers of methyl methacrylate (MMA) and N,N-dimethylacrylamide (DMA) containing 7.5, 15, or 20 wt % DMA were dissolved in a stoichiometric mixture of m-xylylene diisocyanate and ...
Thermodynamic Analysis of the Phase Separation during the Polymerization of a Thermoset System into a Thermoplastic Matrix. II. Prediction of the Phase Composition and the Volume Fraction of the Dispersed Phase
(John Wiley & Sons Inc, 2004-04)
A thermodynamic simulation of the phase‐separation process of an off‐critical blend, based on a thermoplastic matrix with a reactive epoxy system undergoing polycondensation at a constant temperature, was performed. The ...
Effect of the addition of a polycarbonate on the cure of an epoxy thermoset system
(2001)
During the cure of a thermoset-thermoplastic blend two-phase morphologies may be formed. The phase separation process can be controlled by manipulation of the rate of polymerization of the thermoset system. In this work, ...
