The synthesis and characterization of a novel fixative, guar gum-graftpoly(acrylamide-co-diallyldimethylammonium chloride) (GG-g-p(AM-coDADMAC)) polymer is described. The grafted polymer proved to be effective at adsorbing hydrophobic wood resin particles onto papermaking fibre surfaces, thus removing wood resins from the water phase where they have a tendency to aggregate and form troublesome ...

A novel, low-cost and direct green synthesis strategy was developed for the preparation of polymer composite spheres composed of silver nanoparticles (AgNPs) decorated on the polymer colloids in a raspberry-like fashion. The polymer colloids were employed as both the reductant and the substrate support. The environmentally benign reaction system consists of AgNO3, polymer spheres and an ethanol...

A novel organic polymer composite for the encapsulation of metal catalysts and applications to synthesis are described here.

Zoogloea ramigera 115 synthesized large amounts of matrix polymer from fructose, galactose, glucose, lactose, mannose, soluble starch, and sucrose when these carbohydrates were used as supplements to a chemically defined medium. All of them supported polymer synthesis to the extent that cultures thickened to a gel. Concentration of carbohydrate nutrients in the range 0.5 to 2.0% was not a criti...

We evaluated the adsorbability and selectivity of (S)-valine anilide imprinted molecularly imprinted polymer (MIP) using a batch procedure that is both independent and precise. This study revealed important information about the relationship between the performance of MIPs and experimental factors such as the components of MIP synthesis and a reaction solvent. Herein, we also describe the probl...

We propose an automaton, a theoretical framework that demonstrates how to improve the yield of the synthesis of branched chemical polymer reactions. This is achieved by separating substeps of the path of synthesis into compartments. We use chemical containers (chemtainers) to carry the substances through a sequence of fixed successive compartments. We describe the automaton in mathematical term...

Conducting polymers represent an important class of functional organic materials for next-generation electronic and optical devices. Advances in nanotechnology allow for the fabrication of various conducting polymer nanomaterials through synthesis methods such as solid-phase template synthesis, molecular template synthesis, and template-free synthesis. Nanostructured conducting polymers featuri...

A solvent-free synthesis of 1,4-disubstituted-1,2,3-triazoles using neat azides and alkynes and a copper(I) polymer supported catalyst (Amberlyst) A21*CuI) is presented herein. As it provides the products in high yields and purities within minutes, this method thus being characterized as a "flash" synthesis, and was exemplified through the synthesis of a 24-compound library on a small scale.

Nanophase separation into hydrophobic and hydrophilic domains in commercial perfluorosulfonic acid polymers promotes high conductivity by forming proton-conductive channels within a matrix. To transfer this beneficial phase to phosphonic functionalized ionomers, we combine phosphonated polypentafluorostyrene flexible polyoctylstyrene di-block-co-polymer. We introduce stepwise approach, includin...

A polymer is broadly defined as a substance made up of many linked atoms or smaller molecules. Unlike small molecules, polymer properties can vary considerably depending on the method of synthesis. measurement technique. and experimental conditions. As such, knowing additional informatio n about the polymer of interest can be helpful when searching for specific information. This chapter outline...
