WebThere are two methods by which polymers are made: Addition polymerisation. Condensation polymerisation. In addition polymerisation, alkenes add to themselves. As this addition proceeds further a long molecular chain is formed. The alkene is the repeating unit in the chain (the monomer). The chain itself is the polymer. WebThey are formed when many small molecules join together. This process is called polymerisation. When alkenes join together to form a polymer with no other substance being produced in the reaction, the process is called addition polymerisation. Plastics are polymers and are made by polymerisation. Example: poly (ethene) (often called polythene ... town of glastonbury ct health department

Difference Between Addition And Condensation Polymerization

WebPolymers are substances composed of macromolecules, very large molecules with molecular weights ranging from a few thousand to as high as millions of grams/mole.
