“Bio-Based Monomers and Polymers 2” is the third Hanser eCampus course in a series covering bio-based monomers, polymers, and sustainable materials. It covers the practical feedstocks and manufacturing processes, characteristics, and applications for bio-based plastics derived from natural oils (such as soybean oil), bio-based polyols, and cashew nutshell liquid. The production of bio-polyurethanes in particular, both from bio-based and from petro-based diisocyanates is discussed. Both monomer and polymer sourcing and synthesis are described, including their structures and how these influence key properties. Property enhancements such as via copolymerization and addition of additives or reinforcing fibers are identified and evaluated. Comparisons with petro-based polymer alternatives are made to explain where such bio-based polymers hold key advantages in areas such as mechanical properties, biodegradability, carbon footprint, or economics. The course contains many questions to test the student’s comprehension and recall of each learning goal. It is recommended that students taking this course have a background of high-school-level organic chemistry if they are to complete it independently. Module list: 1. Soybean Oil 2.
