Alkenes are reactive and so are useful for making many other substances including polymers.. Polymers have very large molecules. When alkenes join together to form a polymer with no other substance being produced in the reaction, the process is called addition polymerisation. Addition or chain polymerisation can be divided into 3 steps – initiation, propagation, and termination. Any condensation process, which results in the formation of polymers, is the condensation polymerization. Polymers are very large molecules. Addition polymers Alkenes.
