Abstract
A blended electrophilic material with a first component having a functionality of at least three and a second component having a functionality of two is mixed with a nucleophilic material. The blended electrophilic material cross-links with the nucleophilic material to form a non-liquid, three dimensional structure which can applied, e.g., as an adhesion barrier.
Claims14
A method comprising:
- providing a blended electrophilic material comprising a first poly(ethylene glycol) PEG component having a functionality of at least three and a second PEG component having a functionality of two;
- providing a nucleophilic material, separate from the blended electrophilic material, which upon mixing with the blended electrophilic material, cross-links with the blended electrophilic material to form a non-liquid, three dimensional structure;
- and
- mixing the blended electrophilic material and the nucleophilic material to form the non-liquid, three dimensional structure.
