Webpolymer: [noun] a chemical compound or mixture of compounds formed by polymerization and consisting essentially of repeating structural units. 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.
WebJan 16, 2024 · Elastomers are elastic materials with high flexibility and low strength molecular bonds (like rubber). Polymer fibers consist of polymer chains that have stronger molecular bonds than elastomers.
