The copolymer VAMA was synthesized from vinyl acetic and maleic anhydride. A new all-polymeric blend with a high dielectric constant (ε) has been developed by blending polyvinylidene fluoride (PVDF) with vinyl acetic-maleic anhydride modified polyamide (PA66-g-VM). The blend shows high dielectric constants (εblend = 20) and excellent mechanical properties. The SEM investigations suggest that th...
This study includes the design, synthesis and characterization of 1,2-phenylenediamine (o-PDA) functionalized maleic anhydride (MA)-vinyl acetate (VA) copolymer-based conjugate to develop a new formulation. The molecule is fluorescent dye that allows designing chemotherapeutic polymeric molecules. Poly(maleic anhydride-alt-vinyl acetate) [Poly(MA-alt-VA)] was obtained via charge transfer comple...
In this work, the influence of three types of styrene maleic anhydride (SMA) oligomers on the adhesion of polystyrene wood plastic composites (WPC) was investigated. The composites were processed on a twin-screw co-rotating extruder below 200°C using 20 wt% of wood flour. The styrene maleic anhydride with different content of maleic anhydride groups, 30%, 25% and 20% (w/w) and levels of 1, 2 an...
Allyl propionate-maleic anhydride-styren terpolymer has been modified with glycerin in order to prepare a new cross-linked functional polymer sorbent. The synthesized cross-linked polymer sorbent has a network structure and contains carboxylic acid, carbonyl, hydroxy, and ester groups, all of which are capable of interacting with metal ions. The sorption behavior of UO 2 ions under optimum sorp...
A binary copolymer water treatment agent was synthesized by using maleic anhydride and sodium allyl sulfonate as raw materials ammonium persulfate initiator. The scale inhibition dispersion properties of the were studied through static experiments. results show that has excellent performance. Moreover, polymer is an environment-friendly with good application prospects.

This study experimentally investigates the effect of processing parameters on mechanical properties of injection molded copolymer. This paper presents an experimental study on the effects of processing parameters including melt temperature, injection pressure and amount preliminary materials on tensile strength of injection molded copolymer PP-WGRT. Polypropylene (PP - supplied by T.P.C of Iran...
Preparation and Characterization of Poly (urea- Formaldehyde) Walled Dicyclopentadiene Microcapsules
Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene maleic anhydride copolymer (SMA), and the addition...
