    Abstract: A method for increasing a mean particle size of a 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidine is provided. The method comprises forming a mixture comprising a feedstream of the 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine, and a solvent composition comprising an organic solvent and water, wherein the organic solvent is capable of at least partially dissolving the 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidine and forming an adduct with the 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidine. Then the mixture is heated at a temperature and for a time effective to decompose the adduct and form a 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidine product having a mean particle size greater than 5 microns. The 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidines with increased particle size are useful for producing polymers.

  • Patent number: 6517343
    Abstract: A curable composition is placed on a candle, and then the composition is exposed to curing conditions such as ultraviolet light, to thereby cure the coating composition and provide a candle having a cured coating. The curable composition may be the reaction product of TMPTA (trimethylolpropanetriacrylate), itself the reaction product of trimethylolpropane and acrylic acid) and oleyl amine (an unsaturated primary amine having eighteen carbons). The candle may be made of wax or a gelled solvent, i.e., a mixture of gellant and solvent, particularly a hydrocarbon or other low polarity solvent. The undiluted coating may be applied by spraying on the oily surface of the candle. Ultraviolet cure of the coating occurs in 1-2 seconds.

  • Patent number: 6509091
    Abstract: Disclosed is a polyethylene glycol modified copolyester fiber that has exceptional moisture management characteristics and that can be formed into exceptionally comfortable fabrics. The copolyester fiber includes polyethylene terephthalate in an amount sufficient for the copolyester fiber to possess dimensional stability properties substantially similar to those of conventional, unmodified polyethylene terephthalate fibers, polyethylene glycol in an amount sufficient for the copolyester fiber to possess wicking properties that are superior to those of conventional, unmodified polyethylene terephthalate fibers, and chain branching agent in an amount less than about 0.0014 mole-equivalent branches per mole of standardized polymer.
