Zinc-Mediated Living Cationic Polymerization

ACS Macro Letters, 2023
Here, we present a facile and robust method for living cationic polymerization using zinc wire as a catalyst precursor. Well-defined poly(vinyl ether)s with various molecular weights and narrow molecular weight distributions (Đ < 1.10) can be achieved at room temperature.

Redox Intitiated Cationic Polymerization

Macromolecular Symposia, 2009
AbstractTwo novel redox initiator systems have been developed for carrying out the cationic polymerizations of vinyl and heterocyclic monomers. The initiators are based on various onium salts as the oxidant together with an alkylborane or an organosilane as the reducing agent.

Electro‐Controlled Living Cationic Polymerization

Angewandte Chemie, 2018
AbstractCationic polymerizations have long been industrialized; however, stimulus‐regulated cationic polymerization remains to be developed. An electrochemically controlled living cationic polymerization is presented for the first time. In the presence of external potential and organic‐based electrocatalyst, a series of monomers can be polymerized ...

Thermodynamics of cationic polymerization. 1. Cationic propagation

Acta Polymerica, 1988
AbstractLatterly, the formation enthalpies were determined for many carbocations by means of thermochemical methods. Therefore a thermodynamical view is possible for the propagation reactions of the cationic polymerization to a larger extent.

Cationic polymerization of chloral

Polymer Science U.S.S.R., 1975
Abstract It was found possible to polymerize chloral using cationic catalysts. In contrast to anionic polymerization, chloral is polymerized at a much lower rate with cationic catalysts and the polymer formed has a variable morphology.

Cationic graft polymerization lithography

SPIE Proceedings, 2003
Cationic graft polymerization lithography is a variation of top surface imaging schemes. This technique uses a spin-coated, inert polymer film as a photoacid generator carrier. UV exposure is used to generate acid in the top surface of the film. A vapor-phase reaction between the generated acid and a silicon-containing monomer occurs in the exposed ...

Photoinitiated Cationic Polymerization

1999
This paper describes the latest developments in the photoinitiating systems, based on onium salts, for cationic polymerization. The goal is, furthermore, to show differences as well as parallels between systems for different modes of photoinitiation.
