The simplest block copolymer is the “diblock” where one end of the chain is one type of polymer, while the other end is another type. Triblocks would add yet another block of polymer to the chain to form an A-B-A or B-A-B structure. Comonomer blocks can also be added as ...
What Is Spandex Fabric? Spandex is a synthetic fabric that is prized for its elasticity. Contrary to popular belief, the term "spandex" is not a brand name, and this term is used to generally refer to polyether-polyurea copolymer fabrics that have been made with a variety of production pr...
Starch, a polysaccharide produced by plants forenergy storage, is commonly used in biodegradable polymeric composites. When reinforced with cellulose fibers from jute, bamboo, sisal, cotton, or fibers of the same polymer (self-reinforced composites), starch-based materials gain improved strength, durab...
Elastane: Elastane is the general term used to refer to polyether-polyurea copolymer fabrics. This term is synonymous with spandex, and it can also refer to the substance that DuPont has branded as Lycra. Spandex: Contrary to popular belief, spandex is not a brand name; it is, in fact,...
