A new radical mechanism of nucleotide polymerization is found. The finding is based on the Car-Parrinello molecular dynamics computations at 310 K with an additional spin-spin coupling term for 31P and 1H atoms and a radical pair spin term included. The mechanism is initiated by a creation of a high-energy spin-separated Mg-ATP complex in a triplet state in which the Mg prefers an uncommon chel...
Aqueous catalytic polymerization may seem like a contradiction at first sight. The high water sensitivity of Ziegler or Phillips catalysts applied commercially for the production of polyolefins is well known. However, water offers a unique combination of properties as a medium for polymerization reactions: A high heat capacity, which enables an effective transfer of the heat of polymerization. ...

In current study,a hydrogel based on biocompatible polymerwas prepared. The functionalization of polyvinyl alcohol (PVA)with epichlorohydrin(ECH) to produce epichlorohydrin-g-polyvinyl alcohol (PVA/ECH) as a suitable macroinitiator for atom transfer radical polymerization (ATRP) reaction was investigated.ThenN-vinyl pyrrolidone (NVP) waspolymerized on the surface of macroinitiatorin presence of...
The synthesis of a linear polyisobutylene is achieved for the first time by free radical polymerization. reaction was performed in environmentally friendly conditions, i.e., an aqueous medium using cyclodextrin solubilizer, around room temperature. This mild and straightforward polymerization resulted predominantly polymer with low dispersity. Isobutylene also copolymerized acrylamide via this ...
