“…In the case of DMDAAC‐PC copolymers, the peaks (c) at the range 3.16–3.28 ppm are corresponding to the H atoms of the CH 3 and CH 2  which link to the nitrogen atom. For HEMA‐PC copolymers, the peak (d) at 4.81 ppm is corresponding to the H atoms of the OH in HEMA . The characteristic peaks of above‐mentioned H atoms would not appear at these positions if the monomer molecules did not polymerize which further verified the characteristic structure of the synthesized products.…”

In this work, three kinds of HPEG-type polycarboxylate superplasticizers (PCs) were synthesized with three kinds of typical functional monomers: [diallyl dimethyl ammonium chloride (DMDAAC), 2-hydroxyethyl methacrylate (HEMA), and 2-(dimethylamino) ethyl methacrylate (DMAM), respectively. The effects of montmorillonite clay on the fluidity of cement/PC pastes were investigated. It was found that the fluidity was negatively affected by the clays in the order: DMAM-PC < HEMA-PC < conventional PC (CPC) < DMDAAC-PC. The DMAM-PC was found to disperse cement well even in presence of montmorillonite clay. The dispersion performance of DMDAAC-PC was much more effectively affected by clay due to the reaction between ammonium and montmorillonite. More study including mortar fluidity, adsorption behavior and morphology of the cement samples were investigated in details. Thermogravimetric analysis and X-ray diffraction experiments allowed us to observe the influence of PCs on the hydrated products.

“…Other approaches to producing polymers containing cubane in the backbone of the polymer scaffold were evaluated by use of additional monomers. Related to his medicinal applications, Mahkam used silane and hydroxy containing methacrylates with cubane-1,4-bis(methacryloyloxyethyl)carboxylate 200 as a cross-linking agent to perform free radical copolymerization. , When analyzed the polymers containing 200 had T g values higher than the polymers without any cross-linking monomer.…”
