Abstract
A method of making hollow fiber filtration modules including potting an end portion of a plurality of hollow fiber membranes with a multi-pack, solvent-free curable composition. The curable composition includes a Michael donor, a Michael acceptor, and a Michael reaction catalyst.
Claims20
A method of making a hollow fiber membrane module, comprising:
- preparing a mixture of a multi-pack, solvent-free curable composition by combining a multi-functional Michael donor, a multi-functional Michael acceptor, and a Michael reaction catalyst,
- introducing the mixture of the curable composition into at least one end portion of a plurality of hollow fiber membranes, and
- allowing the curable composition to solidify and cure, thereby potting the end portion of the plurality of hollow fiber membranes.
A hollow fiber membrane module, comprising
- a plurality of hollow fiber membranes having at least one end portion potted with a potting composition,
- wherein the potting composition comprises a reaction product of
- a multi-functional Michael donor,
- a multi-functional Michael acceptor, and
- a Michael reaction catalyst.
