Patent number: 6235916Abstract: Novel compounds derived from traditional semi-drying and non-drying oils featuring internally plasticizing and crosslinkable properties are disclosed and claimed. Preferred embodiments include acrylate or methacrylate esters of hydroxy long-chain olefinic compounds derived from castor oil or lesquerella oil. A process for the preparation of the novel compounds is also disclosed, which involves esterification reaction of ethylenically unsaturated carboxylic acids or its derivatives with substituted hydroxy long-chain olefinic compounds. These compounds are suitable for forming latices, which form films at low minimum film forming temperatures (MFT) ranging from −5 to 10° C. and cure to above ambient glass transition (Tg) polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions. These latices are therefore useful in waterborne coatings, contact and pressure sensitive adhesives, and inks.Type: GrantFiled: December 24, 1996Date of Patent: May 22, 2001Assignee: University of Southern MississippiInventors: Shelby Freland Thames, Kamlesh Gopichand Panjnani, Rajan Hariharan, Zhiyu Wang

Patent number: 6072063Abstract: Ester quats of the formula (1) below are described: ##STR1## where RCO is an aliphatic acyl radical having 6 to 22 carbon atoms, R.sup.1 is a methyl radical, R.sup.2 is a C.sub.1 -C.sub.6 -alkyl radical, R.sup.3 is a C.sub.3 -C.sub.6 -alkyl radical and X.sup.- is a halogen anion. They are prepared by quaternizing the corresponding carboxylic acid ethanolamine ester compound with a methyl halide in the absence or presence of solvents. The ester quats of the invention have a low melting point. Furthermore, even in high concentration they are highly water soluble and, on account of their preparation, are obtained in high purity and free from toxic contents. These ester quats can be used in many ways and are suitable, for example, for preparing solid or aqueous formulations having a high surfactant effect.Type: GrantFiled: February 26, 1997Date of Patent: June 6, 2000Assignee: Clariant GmbHInventors: Oliver Eyrisch, Rudolf Aigner
