Crosslinking of collagen with dicarboxylic acids / F. Scholnick in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXVII, N° 9 (09/1992)
[article]
Titre : Crosslinking of collagen with dicarboxylic acids Type de document : texte imprimé Auteurs : F. Scholnick, Auteur ; L. L. Liao, Auteur ; Eleanor M. Brown, Auteur ; Stephen H. Feairheller, Auteur Année de publication : 1992 Article en page(s) : p. 333-338 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : We have studied the crosslinking of collagen in sheepskin by treatment with N-hydroxysulfosuccinimide esters of dicarboxylic acids.The acylating agents are prepared from dicarboxylic acids including suberic (C-8), azelaic(C-9) and sebacic(C-10) acids.These agents are extremely soluble in water and react readily with sheepskin,resulting in increases in shrinkage temperatures before chrome tanning.A descrisption of the synthesis of acylating agents and a discussion of the physical properties of the resulting leathers are presented.

Titre : Use of poly(vinyl stearate) for fatliquoring Type de document : texte imprimé Auteurs : F. Scholnick, Auteur ; L. L. Liao, Auteur ; M. Komanowsky, Auteur ; Paul L. Kronick, Auteur Année de publication : 1993 Article en page(s) : p. 353-357 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Vinyl stearate, a commercially available monomer, was used as a model compound for studying polymeric fatliquoring agents. It was readily polymerized in emulsion by free radical initiation in the presence of retanned, non-fatliquored blue stock. The product showed improvement in mechanical properties such as a 65% increase in elongation at failure and a 75% increase in energy to break with no loss in tensile strength. In addition, improved water repellency and resistance to water penetration were noted as the amount of vinyl stearate offered was increased.
