A method i for forming an epoxidized polymer is provided. The method may include mixing an epoxidized plant oil with a synthetic epoxy resin and crosslinking the epoxidized plant oil and the synthetic epoxy resin using a curing agent. The epoxidized plant oil may be formed via: converting plant oil triglycerides to fatty amide alcohols via aminolysis using primary or secondary amines, converting the fatty amide alcohols to epoxidized fatty amide alcohols, and reacting the epoxidized fatty amide alcohols with vinyl monomers to obtain epoxidized plant oil monomers.
