Résumé : |
The graft polymerization of ethyl and butyl acrylates onto chrome-tanned sheepskins was investigated and the conditions for reproducibly effecting the reaction have been established. For a number of reasons, butyl acrylate w•as found to be the monomer of choice. The product containing 13 percent poly( butyl acrylate), at least partially grafted to the collagen, had an increased thickness, the appearance of having been fatliquored, and a high degree of area stability. In addition, it had not suffered any decreases in shrinkage temperature or strength. The process was also applied to chrome-tanned kangaroo skins with the same beneficial results. |
