Microstructural deformation behaviour in polystyrene-based compatible polymer blend systems
(Elsevier, 1994-05)
Microstructural deformation behaviour in polystyrene-based compatible polymer blend systems was studied using transmission electron microscopy (TEM) and microdensitometry. Four different binary compatible blend systems ...
Toughening mechanisms in thermoplastic-modified epoxies: 1. Modification using poly(phenylene oxide)
(Elsevier, 1993-09)
An epoxy based on the diglycidyl ether of bisphenol A (DGEBA) has been modified with poly(phenylene oxide) (PPO) and cured with piperidine. A two-phase alloy resulted, in which the DGEBA epoxy was the continuous phase. ...
Fatigue craze initiation in polycarbonate: study by transmission electron microscopy
(Elsevier, 1994-08)
Fatigue craze initiation in bulk, amorphous polycarbonate (PC) is investigated by means of transmission electron microscopy. The results agree very well with small angle X-ray scattering measurements of the same set of ...
Three-dimensional solubility parameters and chemical protective clothing permeation. I. Modeling the solubility of organic solvents in Viton® golves
(Wiley Subscription Services, Inc., A Wiley Company, 1993-10-15)
A model based on the polymer solution theory of Flory and Rehner is presented for estimating the solubility of organic solvents in chemical protective clothing (CPC) polymers using three-dimensional (3-D) solubility ...
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 ...
