Sentence examples for main chain polymers from inspiring English sources

Second-order NLO chromophores used for main chain polymers have been designed, synthesized and characterized by 1H NMR and FTIR.

On the other hand, bis(heterocycles) have received a great deal of attention, not only as model compounds for main chain polymers but also because many biologically active natural and synthetic products have molecular symmetry [11 22].

studies of cholestane (COL) and tempol (TPL) spin probes dissolved in mixtures of two different side chain polymers and two different main chain polymers in the plasticizer dibutyl phthalate were performed.

These are: the charged groups of the amino acid side chains such as lysine, arginine, glutamic and aspartic acids, hydroxyl groups of the side-chains in serine, threonine and hydroxylysine; and the carbonyl groups and the N-H groups of side chains and main chain polymers not involved in intramolecular bonding [20].

These results indicated that the copolymer containing PTMC and mPEG segments regulated the surface wettability of its main chain polymer and composition ratio of the macromonomer.

Polymers bearing benzil units in the main chain (polymer I, poly(oxyhexyleneoxy-4,4′-benzilylene) and polymer II, poly(oxy-4,4′-benzilyleneoxysebacoyl) or as pendant side groups (polymer III, poly phenyl methacrylate -co-4-methacryloyloxy-4′-methoxybenzil) were synthesized via polycondensation and free radical polymethacrylate -co-4-methacryloyloxy-4′-methoxybenzil

These side-chain polymers may exhibit behaviour similar to that of main-chain polymers.

Stable organoboron main-chain polymers were prepared by hydroboration polymerization of various diynes with mesitylborane.

In addition, these hyperbranched main-chain polymers could combine the large nonlinearities of hyperbranched polymers and high stability of main-chain polymers, providing a new solution to solve the "nonlinearity-stability" trade off existing in the main-chain polymers to some degree.

By using functional polymers to react with fullerenes, or synthesizing polymers in the presence of fullerenes, various kinds of polymeric fullerenes can be prepared: side-chain polymers, main-chain polymers, dendritic fullerenes, star-shaped polymers, fullerene end-capped polymers, etc.

In this paper, two new series of hyperbranched main-chain polymers, P1 P6, with chromophore moieties as the core were successfully prepared through "A3+B2" approach via simple Sonogashira coupling reaction.
