In making slime, the individual polymer chains are bound together by weak hydrogen bonds. The resulting polymer network is composed of strands of polyvinyl alcohol held together side-by-side by the borate molecules.

Polymer Chain Reaction (PCR): Principle and Applications

Webpolymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or … WebPolymers are large molecules constructed from many smaller structural units called monomers which are covalently bonded together. In chemistry repeating unit is the unit that periodically repeats itself along the polymer chain. Most of the time the repeating unit is nearly equivalent to the monomer.

WebJun 27, 2024 · Chain growth polymerization is also called addition polymerization because monomers are added to the ends of polymer chains. The monomers are attached to the chain in the active site of the growing polymer chain, one monomer at a time. The growth of polymer chains occurs only at the ends. The steps of chain polymerization include, … WebSynthetic polymers are manufactured using chemical reactions that join lots of small molecules together to make long molecules. For example, polycarbonate is a synthetic polymer used to make the ... WebChain transfer is a termination reaction by which the free-radical site of a growing polymer chain is transferred to another molecule: R r · + S → P r + S·.
