  2. Living free-radical polymerization - Wikipedia

    en.wikipedia.org/wiki/Living_free-radical...

    Living free radical polymerization is a type of living polymerization where the active polymer chain end is a free radical.Several methods exist. IUPAC recommends [1] to use the term "reversible-deactivation radical polymerization" instead of "living free radical polymerization", though the two terms are not synonymous.

  3. Living polymerization - Wikipedia

    en.wikipedia.org/wiki/Living_polymerization

    Living polymerization: A chain polymerization from which chain transfer and chain termination are absent. Note : In many cases, the rate of chain initiation is fast compared with the rate of chain propagation, so that the number of kinetic-chain carriers is essentially constant throughout the polymerization.

  4. Radical polymerization - Wikipedia

    en.wikipedia.org/wiki/Radical_polymerization

    In polymer chemistry, free-radical polymerization (FRP) is a method of polymerization by which a polymer forms by the successive addition of free-radical building blocks (repeat units). Free radicals can be formed by a number of different mechanisms, usually involving separate initiator molecules .

  5. Reversible-deactivation radical polymerization - Wikipedia

    en.wikipedia.org/wiki/Reversible-deactivation...

    There is a mode of polymerization referred to as reversible-deactivation polymerization which is distinct from living polymerization, despite some common features. Living polymerization requires a complete absence of termination reactions, whereas reversible-deactivation polymerization may contain a similar fraction of termination as conventional polymerization with the same concentration of ...

  6. Reversible addition−fragmentation chain-transfer polymerization

    en.wikipedia.org/wiki/Reversible_addition%E2%88...

    RAFT is a type of living polymerization involving a conventional radical polymerization which is mediated by a RAFT agent. [8] Monomers must be capable of radical polymerization. [9] There are a number of steps in a RAFT polymerization: initiation, pre-equilibrium, re-initiation, main equilibrium, propagation and termination.

  7. Chain transfer - Wikipedia

    en.wikipedia.org/wiki/Chain_transfer

    The nature of chain transfer reactions is currently well understood and is given in standard polymerization textbooks. Since the 1980s, however, a particularly active area of research has been in the various forms of free radical living polymerizations including catalytic chain transfer polymerization, RAFT, and iodine transfer polymerization ...

  8. Chain-growth polymerization - Wikipedia

    en.wikipedia.org/wiki/Chain-growth_polymerization

    Due to the low PDI and predictable molecular weight, living polymerization is at the forefront of polymer research. It can be further divided into living free radical polymerization, living ionic polymerization and living ring-opening metathesis polymerization, etc.

  9. Copper-based reversible-deactivation radical polymerization

    en.wikipedia.org/wiki/Copper-based_reversible...

    Copper-based reversible-deactivation radical polymerization (Cu-based RDRP) is a member of the class of reversible-deactivation radical polymerization. [1] In this system, various copper species are employed as the transition-metal catalyst for reversible activation/deactivation of the propagating chains responsible for uniform polymer chain growth.
