The role of chain transfer processes in iniferlboron trichloride initiated polymerizations of isobutene

چکیده
Kennedy et al. have introduced mixtures of monoor polyfunctional aralkyl chlorides with BCl, as initiating systems for the polymerization of isobutene'). This so-called inifer technique has been demonstrated to be a valuable method for the production of telechelic polymers2). The mechanism of initiation, which has been suggested for these polymerizations'*2), is in full agreement with the results of our model studies3). The growth of the polyisobutene chain may be interrupted either by chain transfer to inifer [Eq. ( l ) ] or by the termination step shown in Eq. ( 2 ) ' ~ ~ ) .

Thermal effect and role of entanglement and coherence on excitation transfer in a spin chain
We analyze the role of bath temperature, coherence and entanglement on excitation transfer in a spin chain induced by the environment. In Markovian regime, we show that coherence and entanglement are very sensitive to bath temperature and vanish in time in contrary to the case of having zero-temperature bath. That is while, finding the last qubit of the chain in excited state increases by incre...

متن کاملCyclic poly(alpha-peptoid)s and their block copolymers from N-heterocyclic carbene-mediated ring-opening polymerizations of N-substituted N-carboxylanhydrides.
N-Heterocyclic carbene (NHC)-mediated ring-opening polymerization (ROP) of N-substituted N-carboxylanhydride ((N)R-NCA) yields cyclic poly(alpha-peptoid)s with controlled molecular weights (M(n) = 3-30 kg mol(-1)) and narrow molecular weight distributions (PDI = 1.04-1.12). The reactions exhibit characteristics of a living polymerization with minimal chain transfer. This enables the facile synt...
متن کاملSurface-initiated Atom Transfer Radical Polymerization and Solution Intercalation Methods for Preparation of Cellulose-G-PS-G-PAN/MMT Bionanocomposite
Cellulose was modified by polystyrene (PS) and polyacrylonitrile (PAN) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. For this purpose, first, the graft polymerization of styrene (St) onto cellulose fibers was performed by using suspension polymerization and ...
