Title: | STUDY OF SOLVENT DIFFUSION IN POLYMERIC MATERIALS USING MAGNETIC-RESONANCE-IMAGING | Authors: | ERCKEN, M ADRIAENSENS, Peter VANDERZANDE, Dirk GELAN, Jan |
Issue Date: | 1995 | Publisher: | AMER CHEMICAL SOC | Source: | MACROMOLECULES, 28(25). p. 8541-8547 | Abstract: | Magnetic resonance imaging (MRI) has been used to study the diffusion of 1,4-dioxane in poly(vinyl chloride) (PVC) and of acetone (or mixtures of acetone/methanol) in polycarbonate (PC). The results reveal that the system PVC/1,4-dioxane follows the classical Case II theory. The other two systems investigated (PC/acetone and PC with acetone/methanol mixtures) obey Fick's law. In this case, a solvent-induced crystallization takes place after the diffusion front which, at the final stage, leads to a solvent-induced cracking of the material. | Notes: | UNIV LIMBURG,INST MAT ONDERZOEK,DEPT SBG,B-3590 DIEPENBEEK,BELGIUM. | Document URI: | http://hdl.handle.net/1942/3515 | DOI: | 10.1021/ma00129a012 | ISI #: | A1995TH42600012 | Type: | Journal Contribution |
