  • Patent number: 6878797
    Abstract: A process for producing alkali metal polymaleimide salts by alkaline hydrolysis of maleimide polymers prepared by polymerization of maleimide monomers in the presence of a metal oxide and alcohol initiator or a base. In particular, the process produces alkali metal polymaleimide salts with particular ratios of C—N and C—C connected maleimide-derived monomer units which are dependent on the particular initiator used to synthesize the maleimide polymer. The alkali metal polymaleimide salts, which have chelating and anti-scaling properties, are useful as chelating agents and detergent builders and as such are suitable biodegradable replacements for synthetic polymers and sodium polyaspartate.

  • 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.
