Polymers from Renewal Resources: Crosslinking and Thermal Behavior

摘要: The scarcity and high price of crude oil have resulted in research development activities worldwide for the use renewable resources as feedstocks polymers.1 Recently gum rosin from exudate pine trees has been developed a raw material copolyimides other polymers.3–10 Rosin was made to react with maleic anhydride form rosin-maleic Diels-Alder adduct (RMA). RMA found be suitable substitute trimellitic (TMA), key chemical temperature resistant polymers such poly-esterimides, polamideimides copolyimides.2–5 Schuller Lawrence also reported some polyamideimides using material.6–8 Synthesis maleopimaric acid diamines by Aldrich.9 Penczek coworkers synthesis polyesterimides reacting amino alcohols.10
