Hybrid organic-inorganic polymer-polymer composites were prepared by blending with poly(A-vinylpyrrolidone) (PVPr), poly(4-vinylpyridine) (PVPy) and poly(ethyl oxazoline) (PEOx). It was found that the properties of these hybrids depended strongly on the preparation conditions.14... 

There are a number of major, international manufacturers of coagulant and flocculant polymers whose primary markets are high-volume users (i.e., cities, states, and national governments). There are also many smaller regional manufacturers who tend to specialize in niche markets and produce various polymer blends (organic polymers blended with various ratios of inorganic coagulants such as ACH, PAC, and alum). These polymer blends are particularly useful in industrial facilities where process contamination and difficult clarification problems may exist.

Conversion of a membrane material or membrane from one developed for aqueous-inorganic salt separations to one for use In aqueous-organic or organic-organic separations often requires modifications such as copolymerization, polymer blending or radiation grafting onto the membrane surface. These approaches are often difficult, are not fully understood and are not always entirely successful. 

ToF-SlMS is mainly referenced in the characterization of polymers and organic additives and blends [19-26] only few investigations of catalysts are reported in the litterature [27-29]. However, inorganic applications of ToF-SIMS were illustrated by Aubriet et al. [30] who studied the behaviour of the first row transition metal oxides and proposed, for each of them, a reliable methodology of speciation. 

The application area of coatings involves often complex multicomponent compositions comprising various additives both organic and inorganic. Not surprising, polymer blend technology is often employed to yield specific property improvements. Sub-micron polymer particles e.g., PS) can be...
