Estimating the term…
An ester-terminated dimer acid-based polyamide may be blended with a solvent to form a gel. The solvent may be flammable, and a wick may be added to the resulting gel so as to form a candle. Depending on the composition, the candle may be formed into a free standing pillar, or may be better suited to being placed in a container. The solvent may be mineral oil. A solid coating may be placed around the candle, for advantages including to enhance the mechanical stability of the gelled body, and to eliminate the tendency of a gel to have an oily feel and to accept noticeable fingerprints. The solvent which, in combination with the ester-terminated dimer acid-based polymer forms a gel, may be or include a fragrance material, an insecticide or an insect repellent. A wick may or may not be present in this gel, but in any event, the composition provides for the release of the fragrance, insecticide or insect-repellent.
A flammable article comprising a fuel and a solid coating, where the coating encases at least a portion of the fuel.
A flammable article comprising a gel, the gel comprising a gellant and a flammable solvent, the gellant comprising ester-terminated dimer acid-based polyamide (ETDABP).
An article comprising flammable solvent with a flash point ranging from about -15.degree. C. to about 300.degree. C. and an ester-terminated polyamide of formula (1) ##STR10## wherein n designates a number of repeating units such that ester groups constitute from 10% to 50% of the total of the ester and amide groups;
A flammable article comprising ester-terminated dimer acid-based polyamide (ETDABP) and solvent, the solvent having a flash point ranging from about -15.degree. C. to about 300.degree. C. and the ester-terminated dimer acid-derived polyamide being prepared by a method comprising reacting x equivalents of carboxylic acid from diacid or a reactive equivalent thereof, y equivalents of amine from diamine and z equivalents of hydroxyl from monoalcohol or a reactive equivalent thereof, wherein at least about 10% of the carboxylic acid equivalents are from polymerized fatty acid, and monoalcohol is substantially the only monofinctional reactant used to form the gellant, wherein each of x, y and z is greater than 0.
A composition that emits an active substance over an extended period comprising ester-terminated dimer acid-based polyamide (ETDABP) and an active substance, the composition having a consistency of a gel.
A method of forming a coated article comprising the steps
