[72], [73] provided direct evidence of depletion hole of the functionalized chains at an interface by studying the
coupling reaction between deuterated hydrozy terminated PS (dPS-OH) and methyl methacrylate and methacrylic acide copolymer (PMMA-MAA) at a relatively low temperature of 120[degrees]C.
Ideally, the
coupling reaction between silica particles and the rubber network should take place during the tire's molding process.
The development of water-soluble phosphine ligands for
coupling reaction has been an expanding area of research over the past several years.
Sodium naphthionate (3) was connected with diazo of benzidine (2) at low temperature, which was maintained throughout the completion of
coupling reaction. The pH of reaction was maintained at 8.0 and the completion of the reaction was monitored by taking TLC of reaction mixture in ethyl acetate: ethanol 1:1 system.
Compared with adding premade copolymers, in situ reactive compatibilization through
coupling reaction between the functional polymers has become dominant route to improve the compatibility between immiscible polymer blends due to higher compatibilizing efficiency and lower cost (1-5).
General Procedure for Photocatalytic
Coupling Reaction Via Ruthenium Metal Complex.
From our earlier work on the synthesis of a 3-dodecyl-substituted PTV (RR-[C.sub.12]-PTV) via Horner-Emmons reaction as well as Stille
coupling reaction [1], we learned that PTV from the Stille reaction was neither regioregular nor structurally free of defect.
The strong interaction caused by the
coupling reaction could improve the dispersity effect of the palygorskite in the cis-polybutadiene rubber matrix, and the corresponding properties of the resulting nanocomposites are also systematically investigated.
These defects result from the happening of head-to-head (or tail-to-tail)
coupling reaction, instead of regular head-to-tail one, during the polymerization reaction.
PMS was prepared by the reductive
coupling reaction of methyldichlorosilane with sodium metal in toluene under nitrogen atmosphere.
Homolytic benzylation and oxidative
coupling reaction," Journal of Chemistry, vol.
The torque increase, on the other hand, can partially result from the PBT
coupling reaction but also from branching/crosslinking of the siloxane phase, as was the case for the SiH-functional siloxane.
