By using an appropriate cationic polymerization
system, novel polymers could be produced that retained unsaturation derived from the biobased starting material.
As a result of the much higher reactivity of the vinyl ether group compared to the unsaturation derived from the bio-based compounds and the ability to tailor the cationic polymerization
process, polymerization was exclusively limited to vinyl ether groups.
Abstract Novel, partially bio-based poly(vinyl ether) copolymers derived from soybean oil and cyclohexyl vinyl ether (CHVE) were produced by cationic polymerization
and investigated for application as alkyd-type surface coatings.
For these reasons, in this study we investigated in more depth the cationic polymerization
of EA-OH by using several initiators ([BF.
Depending on the type of active centre, chain-growth Polymerization can be divided into free-radical, anionic, and cationic Polymerization
Crick reaction has been employed in combination with living polymerization techniques such as ring-opening polymerization (ROP), ring-opening metathesis polymerization (ROMP), cationic polymerization
, nitric-oxide mediated radical polymerization (NMP), atom transfer radical polymerization (ATRP), and reversible addition fragmentation chain transfer polymerization (RAFT).

RS Butyl rubber is created by polymerizing isobutene with small amounts of isoprene at roughly -100[degrees]C, using cationic polymerization
This talk will examine radiation-induced polymerization studies, describe radical and cationic polymerization
mechanisms, compare electron beam and photo-induced polymerizations, and discuss photoinitiators and their use.
Amines, trialkyl or triarylphosphines, thiophenes act as retarder for cationic polymerization
The cationic polymerization
was performed in the presence of trifluoromethanesulfonic acid (triflic acid) as catalyst, in dichloromethane solution, according to monomer activation mechanism, Fig.
It is well known that the photoinitiated cationic polymerization
of systems containing epoxy compounds presents a number of advantages, in particular lack of inhibition by atmospheric oxygen, post-polymerization in the dark, low shrinkage, high mechanical performance of the cured materials, and good adhesion to various substrates.
