摘要:
Synthesis methods for creating polymeric compounds comprising phenyl derivatives (PD), or PDp i.e., polymers modified with PD, with desired surface active effects are described. The polymer backbone of PDp has structural or performance features that can be tailored to control physical properties of PDp, allowing it to be useful for different applications i.e., tissue adhesives or sealants, adhesion promoting coatings, and antifouling coatings.
摘要:
The present document describes a powder composition comprising a functionalized starch having a single helix V-structure and having a degree of substitution of at least 0.25, and a bioactive agent, forming an inclusion complex with said functionalized starch, where the bioactive agent is within the helix V-structure of the functionalized starch having a single helix V-structure. Also described are the functionalized starch having a single helix V-structure and having a degree of substitution of at least 0.25, methods of making the same and methods of using the same to manufacture the powder composition.
摘要:
An agent for virus inactivation capable of exhibiting inactivation action based on structural destruction such as degradation and decomposition against viruses, which comprises a monovalent copper compound such as cuprous oxide, cuprous sulfide, cuprous iodide, and cuprous chloride as an active ingredient, and a virus inactivation material, which contains the agent for virus inactivation on a surface of a substrate and/or inside of the substrate.
摘要:
A method for obtaining self-cleaning and self-sanitizing surfaces of finished leather, comprising the steps of deposition of two coating layers containing respective active mixtures on the finished leather surface, in which a first active mixture comprises a film-forming compound based on polymers and filler, a flow additive compound, a cross-linking compound, an anti-oxidant compound and an aqueous dispersion, and a second active mixture comprises a water-based auxiliary flow additive compound, a silicone emulsion, a solvent aliphatic prepolymer, a photo-catalyst compound, a water repellent agent, a biocide action powder agent and solvent agents and/or wetting agents and/or dispersing agents and/or anti-foam agents.
