Rheological behavior of solutions of amphiphilic acrylic copolymers in mixed solvents
(Wiley Subscription Services, Inc., A Wiley Company, 1996-06-13)
A descriptive model was developed, using viscometry and light scattering, that explains the anomalous rheological behavior of solutions of amphiphilic acrylic copolymers upon the addition of water. The rheological behavior ...
The toughening of polyamide-6 by brominated poly(isobutylene-co-p-methylstyrene): fracture and toughening mechanisms
(Elsevier, 1993-11)
A study on the toughening of polyamide-6 (PA-6) with a new elastomeric modifier, brominated poly(isobutylene-co-p-methylstyrene) (BrXP-50), was conducted. Morphological analyses and mechanical tests were combined to evaluate ...
Modeling the effect of the curing conversion on the dynamic viscosity of epoxy resins cured by an anhydride curing agent
(Wiley Subscription Services, Inc., A Wiley Company, 2010-02-05)
Published curing profiles of epoxy resins mixed with an anhydride curing agent and subsequently crosslinked were reanalyzed with a modified sigmoidal model to describe the dynamic viscosity accompanying resin curing. The ...
The determinants of divalent/monovalent selectivity in anion exchangers
(Elsevier, 1983-04)
This research demonstrates that it is the distance of fixed-charge separation in the resin which is the primary determinant of divalent/monovalent selectivity. Anion resins, particularly acrylics and epoxies, with closely ...
