Abstract
This invention relates to novel rosin-fatty acid vinylic polymer compositions which exhibit properties that make them useful for formulating moisture vapor barrier coatings for paper and other cellulosic base materials. In particular, this invention relates to rosin-fatty acid vinylic polymer moisture barrier coatings obtained from the addition polymerization reaction of a mixture of rosin and fatty acid and a mixture of (meth)acrylic and vinylic monomers.
