Polysaccharides as initiators of nucleic acid polymerization
Quantum-chemical calculations and in vitro experiments have demonstrated that polysaccharides are able to adsorb mononucleotides due to the formation of hydrogen bonds. The subsequent dehydration of polysaccharide-nucleotide complexes in the physiologically acceptable temperature range results in the creation of “correct” DNA polymers that are “recognized” by the specific DNA-polymerases. DNA f...
متن کاملkinetics of waterborne alkyd/acrylic hybrid resin free radical polymerization by two systems of redox and thermal initiators
kinetics of radical polymerizations of waterborne alkyd/acrylic hybrid resin via batch mini-emulsion technique was studied using redox initiators (tbhp/fe2+/edta/asac and tbhp/fe2+/edta/sfs) at relatively low temperatures and thermal initiators (bpo, kps and aibn) at higher temperatures to seek the most suitable initiator system. at the end of all reactions the unreacted monomer content was r...
متن کاملThe efficiency of alkyl halide initiators in carbocationic polymerization
This scheme has been used to explain qualitatively that neither alkyl halides yielding very unstable (i. e. reactive) wbenium ions nor alkyl halides yielding very stable (i. e. unreactive) carbenium ions are efficient initiators. In the fiist case step (1) and in the second case step (2) is unfav~rable~.~). Other authors criticized this conclusion and offered alternative interpretations for the...
متن کاملMiniemulsion polymerization of styrene in the presence of macromonomeric initiators
Macromonomeric azo initiators (macroinimers, MIM) which have the properties of macromonomers, macrocrosslinkers and macroinitiators in a macrostructure were used in miniemulsion polymerization of styrene in the presence or absence of any other stabilizer and initiator. MIMs were prepared from the reaction of 4,40-dicyano-4,40-azovaleryl chloride, with poly(ethylene glycol) (PEG) of different mo...
متن کاملZinc anilido-oxazolinate complexes as initiators for ring opening polymerization.
Three new anilido-oxazolines, ortho-C(6)H(4)(NHAr')(4,4-dimethyl-2-oxazoline) [Ar'=2,4,6-trimethylphenyl, HNPh(TriMe)Oxa (1); 2,6-diisopropylphenyl, HNPh(DiiPr)Oxa (2); 2-methoxyphenyl, HNPh(OMe)Oxa (3)], have been prepared. Reactions of 1 or 2 with one molar equivalent of ZnEt(2) in tetrahydrofuran or hexane solution give the zinc ethyl complexes (NPh(TriMe)Oxa)ZnEt (4) and (NPh(DiiPr)Oxa)ZnEt...
