Abstract:
An antistatic composition comprises (a) at least one ionic salt consisting of a nonpolymeric nitrogen onium cation and a weakly coordinating fluoroorganic anion, the conjugate acid of the anion being a superacid; and (b) at leat one thermoplastic polymer. The composition exhibits good antistatic performance over a wide range of humidity levels.
Abstract:
A water- and oil-repellent, antistatic composition comprises (a) at least one nonpolymeric ionic salt consisting of (i) at least one cation selected from the group consisting of monovalent metal cations, divalent metal cations, and organic onium cations, and (ii) at least one weakly coordinating anion, the conjugate acid of the anion having an acidity greater than or equal to that of a hydrocarbon sulfonic acid, and with the proviso that the anion is organic or fluoroorganic when the cation is a metal; (b) at least one fluorochemical repellency-imparting additive or repellent; and (c) at least one insulating material. The composition exhibits good antistatic and repellency characteristics.
Abstract:
A polyester fiber obtained by depositing a specific amount of a finishing agent comprising a combination in a specific proportion of (1) and aliphatic ester having a molecular weight of 300 to 800 and/or a mineral oil having a Redwood viscosity at 30 DEG C of 40 to 500 seconds, (2) a polyether having a structure comprising ethylene oxide units and propylene oxide units, (3) a nonionic surfactant, and (4) an ionic surfactant on a polyester fiber which comprises at least 90 wt.% polytrimethylene terephthalate and has a difference in refractive indices of 0.025 or higher. The polytrimethylene terephthalate fiber having the specific finishing agent adherent thereto and having a low coefficient of friction is capable of highly smoothly passing through processing steps after spinning, e.g., winding after spinning, stretching, unwinding from a bobbin or cheese, false twisting, weaving, etc. As a result, a polytrimethylene terephthalate fiber excellent in smoothness, wearing resistance, bindability, and antistatic properties is obtained.
Abstract:
The invention concerns a stable oil-in-water microemulsion, whereof the drop dimension ranges substantially between 10 and 100 nm. Said microemulsion contains a) between 25 and 50 wt. % of C12-22 fatty acid methylester; b) between 10 and 20 wt. % of sulphosuccinic acid ester; c) between 0.5 and 10 wt. % of non-ionic emulsifiers, and optionally other accessory agents and additives.
Abstract:
A modified carbon product is described which comprises carbon having attached at least one organic group wherein the organic group comprises a) at least one aromatic group or a C1-C12 alkyl group, and b) a group having the formula -AG-Sp-LG-Z, wherein AG is an activating group, Sp is a spacer group, LG is a leaving group, and Z is a counterion, and wherein the aromatic or the C1-C12 alkyl group is directly attached to the carbon, and wherein the organic group is present in any amount. The present invention also relates to ink and coating compositions comprising these modified carbon products.
