Abstract
Compositions useful for preparing pressure sensitive adhesives, coatings, and/or films are provided, along with methods of making and using the same. The compositions are made from renewable, plant-based materials. The compositions comprise plant oil triglycerides that are polymerized and crosslinked to yield polymer matrices. Plant-based carriers and/or tackifiers can be used in the invention, including epoxidized plant oil triglycerides, acrylated epoxidized plant oil triglycerides, and dihydroxylated plant oil triglycerides. Natural tackifiers such as rosin esters and terpenes can also be used in the compositions. Dihydroxylated plant oil triglyceride tackifiers for use in biobased and synthetic adhesives are also provided.
