- Abstract
- Porous network structures were prepared by in situ polymerisation of a mixture of N-phenylmaleimide and 1, 1'-(methylenedi-4,1-plienylene)bismaleimide (95:5 w/w) in poly(vinylidene difluoride-co-hexafluoropropylene) (PVDH). The mixture of the maleimide monomers was found to form thermoreversible gels with PVDH. Thermodynamic analysis of the gelation process using calorimetry data indicated the formation of complexes of N-phenylmaleimide and vinylidene difluoride repeat units with a molar ratio of 1:2, respectively. PVDH formed optically clear solutions in the mixture above the gelation temperature, observed at 80-120 degreesC depending on composition. Polymerisation of the maleimides was induced by increasing the temperature to 250... (More)

PVDH formed optically clear solutions in the mixture above the gelation temperature, observed at 80-120 degreesC depending on composition. Polymerisation of the maleimides was induced by increasing the temperature to 250 degreesC. During polymerisation, the resulting polymaleimide phase separated from the PVDH melt. A morphological study by microscopy revealed that blends with 80 wt% PVDH contained continuous networks of crosslinked polymaleimide. The porous networks were collected after removing the PVDH by solvent extraction. Thermogravimetrical analysis of the polymaleimide networks under N-2 atmosphere showed that the onset of weight loss occurred at 380 degreesC. These networks may thus be used to prepare thermally stable membranes. (Less)
