This study aims to evaluate the impact of adding a novel tricyclodecane dimethanol diacrylate comonomer on flexural strength (FS) and (IS) heat-cure denture base resin at 10% 20% (v/v) concentrations. To test FS IS, sum total 150 bar-shaped specimens were prepared according standard specifications. For FS, subjected three-point bend with span length 50 mm. Charpy’s was executed 60 The measured ...

This review summarizes the state of the art in the synthesis of well-defined glycopolymers by Reversible-Deactivation Radical Polymerization (RDRP) from its inception in 1998 until August 2012. Glycopolymers architectures have been successfully synthesized with four major RDRP techniques: Nitroxide-mediated radical polymerization (NMP), cyanoxyl-mediated radical polymerization (CMRP), atom tran...

Following an approach developed in our group to incorporate tetrathiafulvalene (TTF) units into conjugated polymeric systems, we have studied a low band gap polymer incorporating TTF as a donor component. This polymer is based on a fused thieno-TTF unit that enables the direct incorporation of the TTF unit into the polymer, and a second comonomer based on the diketopyrrolopyrrole (DPP) molecule...

The swelling and shrinking behaviors of a series of poly(N-isopropylacrylamide) (PNIPA) hydrogels are studied in aqueous solutions of sodium dodecylbenzenesulfonate (SDBS). Between 0 and 3 mol % 2-acrylamido-2-methylpropanesulfonic acid sodium salt (AMPS) is used as an ionic comonomer in the hydrogel synthesis. It is shown that the collapsed PNIPA gels in water at 52°C start to swell above a cr...

A series of polystyrene-based cationic copolymers (PSCC) were synthesized by copolymerization of styrene and cationic comonomer vinylbenzyl trimethylammonium chloride (VBTMAC). These copolymers can be used as internal paper sizing agents in a broad pH range. The effect of charge density on the PSCC colloid properties was investigated. It was found that at room temperature the PSCC could change ...

The most efficient plastic solar cells comprise a blend of conjugated polymer and a suitable electron acceptor, typically a fullerene derivative. Therefore narrow-bandgap conjugated polymers are currently sought for the fabrication of such devices. A significant challenge is being able to predict device function and performance from consideration of the molecular connectivity and dimensions of ...
