Grafting, onto polymer

After photopolymerization of a certain monomer for a given time, the polymerization mixture was poured into excess precipitant to isolate the polymer, which was then extracted with a solvent to separate the polymer grafted onto the PSG from the homopolymer. 

Transfer to polymer may occur by addition of the growing radical end to a double bond of the polymer chain, or it may occur by II atom abstraction from an active H atom of the chain. H atoms in the a position to a double bond (C=C or C=0) or an ether linkage are easily abstractable and thus lend themselves to polymer transfer reactions. The transfer reaction to polymer may be intramolecular or it may be intermolecular. Both have been demonstrated. In the case of intermolecular transfer the demonstration has been made of the productioTi of graft polymers. The method is to polymerize a monomer in the presence of inert polymer of a different composition. " The final product will contain the inert polymer with the new polymer grafted onto it. 

The enantiomers of phenylalanine anilide were analyzed on an imprinted poly(EDMA-co-MAA] polymer grafted onto an ITO glass electrode based on the chiral discriminative gate effect of the MIP in organic solvents [49]. The chiral differentiation implied the evaluation of the effect of phenylalanine anilide enantiomers on the faradic current of redox species (ferrocene], effect caused by a... 

Mixed bmshes of hydrophobic and hydrophilic polymers grafted onto Au-NPs were also used as stabilizers for styrene droplets. Subsequent suspension polymerization of styrene led to PS particles with Au-NPs on their surface. Such raspberry particles might open new perspectives for superhydrophobic coatings with dual-size roughness. " ... 

Polymer-grafting onto sUica can be usually carried out by activation of silica surface and subsequent radical polymerization with a vinyl monomer. However, we recommend preparing a polymer with a reactive terminal group at one side, and then immobilizing it onto the silica surface. 

Faers and Luckham [145] also studied the effect of the amount of polymer grafted onto the colloid surfaces. Decreasing the amount of grafted polymer increased the phase separation concentration of polymers at fixed colloid concentration, demonstrating that it is worthwhile to investigate the effect of the presence of brushes in combination with non-adsorbing polymers.

The anion-exchangers described in Tables 6.4, 6.5 and 6.6 are not latex-coated but their exchange groups are mostly in a narrow band near the outside perimeter of the spherical ion-exchange particle. In some instances the ion-exchange part of the particle consists of a functionalized polymer grafted onto the outer surfaces of the substrate. It should be emphasized that these columns work well for all forms...
