Polymer chain reaction
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. Basically, the properties of polymers depend ...

WebThe molecule, which takes part in the chain transfer reaction, is called (chain) transfer agent. Solvent SH may react with the growing radical as follows: The initiator may also function as a transfer agent: The monomer is also considered a transfer agent (b carbon atom of the radical chain may be transferred to the unsaturated monomer.) Webpoly(ethene) is the polymer; The C=C double bond in ethene is involved in the polymerisation reaction. It allows ethene molecules to join together to form a single product, so it is an example of ...
