  • MATERIALS HAVING IMPROVED WETTABILITY AND RELATED METHODS OF USE AND MANUFACTURE
    Publication number: 20240075422
    Abstract: In general, the subject matter described herein relates to wettable materials that can be used to expose a liquid phase to a gas phase. An example method includes: providing a material including a polymeric substrate and at least one of: a silicate coating disposed over the polymeric substrate; or a polar mineral additive dispersed within the polymeric substrate at a loading from about 1% to about 25%, by weight; and using the material in a chemical process in which the material is at least partially covered by a liquid phase and the liquid phase is exposed to a gas phase.
    Type: Application

  • Hardening of hydrophilic colloids with imidazolium and triazine combinations
    Patent number: 5601971
    Abstract: An improved method of hardening a hydrophilic colloid is detailed. The hardening results in a stronger matrix and less water pickup. These and other advantages are obtained by hardening with a combination of at least one hardener chosen from Formula I either alone or in combination with at least one hardener chosen from Formula II: ##STR1## The substituents are defined.

  • In situ modification of gelatin carboxyl groups
    Patent number: 5391477
    Abstract: A photographic element comprising a modified gelatin whereby the modification results in carbamoyl groups by forming peptide bonds using fast-acting hardener. The derivatization involves initial reaction with a carboxyl activator followed by addition of a substituted amine thereby forming an amide linkage on the polypeptide chain. The resulting gelatin and photographic elements comprising such gelatin have a decreased propensity for water absorption without the loss of sensitometric properties.
