“…As well known, the thermal stability of polystyrene could be greatly improved by copolymerization with maleic anhydride (MA) 9. Styrene maleic anhydride (SMA) copolymers are commonly industrial materials due to their water‐solublity, high functionality, low‐solution viscosity, and water insensitivity.…”

We report on the results of an array comparative genomic hybridization (array CGH) study of 150 karyotypically normal Finnish patients with idiopathic mental retardation and/or dysmorphic features and/or malformations. Using high‐resolution microarray analysis, we sought to identify clinically relevant microdeletions and microduplications in these patients. The results were confirmed using other methods and compared with findings reported in recent publications and internet databases. Small aberrations of potential clinical significance were found in 28 (18.6%) of the 150 patients. Eight of the identified aberrations are known to cause syndromes, 4 affected the X chromosome in males, 4 were familial, and 13 have yet to be associated with a phenotype. This study demonstrates the benefits of array CGH in clinical diagnostics of developmental disorders. Further, our findings give evidence of new syndromes. © 2010 Wiley‐Liss, Inc.

“…TGA analysis of SMA‐ESO polymer shows mainly the characteristics of its building blocks which are ESO and SMA since the TGA analysis results of ESO and SMA are almost identical. TGA analysis of SMA‐MR shows weight loss between 200 and 300°C which probably corresponds to the loss of MR. Another weight loss is observed between 300 and 400°C, probably corresponding to SMA decomposition temperature 23, 24, 25. At the end of TGA analysis SMA‐MR gives 18.93% char yield.…”

In this study, styrene maleic anhydride copolymer (SMA2000, Styrene : Maleic Anhydride 2 : 1) is grafted and/or crosslinked with epoxidized methyl oleate, epoxidized soybean oil, methyl ricinoleate (MR), castor oil (CO), and soybean oil diglyceride. Base catalyzed epoxy‐anhydride and alcohol‐anhydride polyesters were synthesized by using the anhydride on SMA, the epoxy or secondary alcohol groups on the triglyceride based monomers. The characterizations of the products were done by DMA, TGA, and IR spectroscopy. SMA‐epoxidized soy oil and SMA‐CO polymers are crosslinked rigid infusible polymers. SMA‐epoxidized soy oil and SMA‐CO showed Tg's at 70 and 66°C, respectively. Dynamic moduli of the two polymers were 11.73 and 3.34 Mpa respectively. SMA‐epoxidized methyl oleate, poly[styrene‐co‐(maleic anhydride)]‐graft‐(methyl ricinoleate), and SMA‐soy oil diglyceride polymers were soluble and thermoplastic polymers and were characterized by TGA, GPC, DSC, NMR, and IR spectroscopy. © 2009 Wiley Periodicals, Inc.

“…On the other hand, the slight decrease in T m recorded by increasing Sb 2 O 3 content may be accounted for two morphological effects (a decrease in lamellar thickness) and the thermodynamic factors (polymer–polymer interactions). The macromolecular chain motion was apparently restricted due to physical bonding interactions of filler molecules with substrate backbone 19…”

ABSTRACT:The physicomechanical behavior and flammability properties of waste polyethylene and recycled waste rubber powder blend (WPE/RWRP/MA) filled with antimony trioxide (Sb 2 O 3 ), at different contents 5, 10, 15, and 20 wt %, and irradiated with different gamma radiation doses, namely 50, 75, 100, and 150 kGy, were investigated by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and limiting oxygen index (LOI) measurements. Tensile strength, elongation at break, elastic modulus, hardness, swelling properties, and electric conductivity behaviors were also investigated. Experimental results emphasized that Sb 2 O 3 particles retard degradation and flammability of the composite. The LOI increases from 16 to 20.9 with 20 wt % Sb 2 O 3 specimen irradiated with 150 kGy. Improvement in thermal stability at conditions of 15 wt % Sb 2 O 3 and a dose of 75 kGy was demonstrated by TGA.DSC measurements showed that T m significantly increased in the presence of the filler. Mechanical characterization tests showed a significant increase in tensile strength within the range 5-10 wt % Sb 2 O 3 .
