E. Kung, Auteur ; B. E. Maleeff, Auteur ; Robert L. Dudley, Auteur ; Paul L. Kronick, Auteur Année de publication : 1993 Article en page(s) : p. 12-24 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : A surface-active agent, sulfo-N-succinimidyl(SSU) was prepared as a probe for collagen-surfactant interactions.When the probe was mixed with monomeric and dimeric collagen in solution, the alfa1 and beta11 chains reacted to give an electrophoretically homogenous product with increased mobility; the mobilities of the alfa2 and beta12 chains were unaltered.The surfactant appeared to coat fibrils of collagen when dried and viewed in the electron microscope.Experimental evidence forthe chemical reactivity of SSU with hippuryllysine under mild conditions was obtained by NMR.Besides serving as a probe for investigations, SSU might also be a model of a permanent leather lubricant requiring minimal amounts of material.

Ultraviolet-cured coatings without use of acrylates / F. Scholnick in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), LXXXVII, N° 1 (01/1992)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > LXXXVII, N° 1 (01/1992) . - p. 20-25 Titre : Ultraviolet-cured coatings without use of acrylates Type de document : texte imprimé Auteurs : F. Scholnick, Auteur ; Paul L. Kronick ; B. E. Maleeff, Auteur Année de publication : 1992 Article en page(s) : p. 20-25 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Although leather coatings have been prepared by ultraviolet (UV) irradiation of solvent free, 100% reactive acrylate systems, a process which eliminates air pollution and conserves energy, their industrial adoption has been impeded because of possible toxicity of acrylate chemicals. The coatings described here were prepared from non-acrylic oligomers containing maleate and vinyl functionality, which cure rapidly after exposure to UV light. Odorless coatings were formed with good abrasion resistance. Their flexibility was improved by adjustment of formulation. Other physical properties of these coatings including tensile strength and percent elongation are compared with those obtained from acrylateformulations used as reference.
