Abstract
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.
