WebThere are several types of chain transfer reactions; three very common reactions are: Proton transfer to monomer: a β-proton is transfered to a monomer, which becomes the … WebJan 1, 2013 · The polymerization of unsaturated monomers typically involves a chain reaction. In a chain polymerization, one act of initiation may lead to the polymerization of thousands of monomer molecules. Table 7.1 lists the characteristics of chain polymerization as compared with step polymerization.

Radical Chain Polymerization SpringerLink
Webradical being capable of starting a new chain is known chain transfer reaction. The 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 WebChain transfer reactions are especially prevalent in the high pressure radical polymerization of ethylene, which is the method used to make LDPE (low density polyethylene). The 1º-radical at the end of a growing chain is converted to a more stable 2º-radical by hydrogen atom transfer. Further polymerization at the new radical site … WebThe transition state structure for the MA1-D1-1 mechanism (hydrogen atom abstraction from a tertiary carbon atom of a dead polymer chain initiated by M 1 •) is shown in Figure 1.The energy differences of the optimized reactants and products for all possible mechanisms of chain transfer to the D1 dead polymer for MA, EA and n-BA are given in Tables 1, 2, … syntax in nursing theory
