What are polymers?. Alkene. molecules have the ability to add onto one another and produce large molecules these are polymers. . Therefore what are monomers?. The process of these large molecules forming is termed addition polymerisation.. Polymers. . C.X.C objectives. Students should be able to :. Define polymers. Distinguish between addition and condensation as reactions in the formation of polymers. Name examples of polymers formed by:.
