Figure 3. Concentration profiles for different membranes giving an element concentration (in arbitrary units) across the thickness a and b, Cu concentration after exchange. The membranes have been obtained from a low density polyethylene after irradiation grafting with styrene followed by sulfonation. c, Cu concentration after exchange. The membrane has been obtained from a copolymer of tetra-fluororethylene and fluorinated propylene after irradiation grafting with styrene followed by sulfonation. d, Cl concentration after chlorhydratation of dimethyl annio ethyl methacrylate grafted on polyvinylidene fluoride.

Linear low-density polyethylene, LLDPE, was graft modified by incorporation of basic groups from, e.g., dimethylamino ethyl methacrylate, t-butylamino ethyl methacrylate, vinyl pyridine, or allyl urea. These copolymers were then used as reactive components for alloys with acidified polymers, viz., maleated polyolefins... 

Polypropylene, PP, was compatibilized with polyethylene, PE, by grafting PP with a basic monomer and PE with an acidic monomer, then blending the modified polymers. Thus, PP was modified with drmethylamino ethyl methacrylate while PE with methacrylic acid. These were blended in 1 1 ratio to result in high-performing alloys... 

Applications of scanning electron microscopy (SEM) to polymer characterisation and microstructure include studies on the zwitterions-type polymer, poly(3-diethyl methylmethacryloyl ethyl) ammonium persulfonate grafted on to a silica surface by treatment of poly(2-dimethyl amino) ethyl methacrylate [2], polyaniline coated glass fibre fillers with different polyaniline contents [3], and also studies on ultra high molecular weight blends [4] and high-density polyethylene (HDPE)-gamma ferric oxide composite films [5]. 

The original pin support was poly(acrylic acid) grafted onto inert polyethylene, where the carboxylic acid moieties were capped with mono Boc-protected ethyl-enediamine [79]. PS and the extremely hydrophilic polyhydroxyethyl methacrylate and poly(methacrylic add/dimethylacrylamide) were also grafted on [81]. The last grafted support in the Multipin concept is the so-called Lanterns [80], where the actual solid support is PS, which can be functionalized in a similar way to PS gel-type supports.
