Sentence examples for retarded chain from inspiring English sources

Before this point, the effect of organoclay can be negligible, and the increase of chain mobility was ascribed to the decrease of molecular weight of polymer chains, as commonly occurs during dynamic melt processing; after this point, however, a reduced mobility of chains and a retarded chain relaxation were observed and attributed to the formation of a mesoscopic filler network.

The steric bulk around the metal center is key to retarding chain transfer to obtain high molecular weight polyethylene.

However, strong hydrogen bonding may retard chain unfolding during spinning, induce faster relaxation for highly oriented dense-selective skin, and thus reduce gas-pair selectivity.

It seems that the branches retarded local chain mobility of the polymer thereby trapping the penetrant molecules.

The deviation of Tg in the PTN nanocomposites system is ascribed to the interplay of two competing effects; (i) the increase in the local free volume owing to the confining effect of intercalation (enhanced the chain mobility) and (ii) entropic constraint imposed by the stronger interfacial interaction due to the physical jamming of layered clay (retarded the chain mobility).

It is due to the effective chain packing that the motion of longer chain segments is retarded and separates from the local segmental motion in time scale.

In the presence of MFI, β-carotene bleaching was retarded, mainly due to the chain-breaking inhibition of lipid peroxidation by neutralizing linoleic free radical formed.

It is of interest to note that such chain reactions can be retarded by the presence of negative catalysts, more commonly termed inhibitors.

In general, inorganic concentration and composition retarded polymer segmental motions, inhibited polymer chain packing, and increase predicted FFV.

The analysis of isothermal crystallization kinetics shows that the crystallization of IPEUs is retarded by the introduction of IBPA chain extender with bulky pendent groups.
