[source] Solid state structure and mechanical properties of melt mixed poly(trimethylene terephthalate)/polycarbonate blendsJOURNAL OF APPLIED POLYMER SCIENCE, Issue 6 2008I. González Abstract Poly(trimethylene terephthalate) (PTT)/poly (carbonate of bisphenol A) (PC) blends were obtained in the melt state by direct injection molding and also by extrusion followed by injection molding. The blends rich in PTT were monophasic, while the blends rich in PC were biphasic with the two components of the blends present in both phases. Both the monophasic and biphasic blends were partially miscibilized, and also partially reacted, as observed by FTIR. The extent of the reaction was greater in previously mixed blends. The observed synergism in the modulus of elasticity was attributed to the increased orientation of the blend components upon blending. Although decreases in elongation at break were observed and attributed to degradation of PTT, the blends were clearly ductile and compatible. This was a consequence of either their monophasic structure, or of the presence of the two components in the two phases of the blends. © 2008 Wiley Periodicals, Inc.

Infrared spectroscopy indicates that the prepared organotin carboxylates possess chain polymer structures. NMR data show that the mono- and dichloro derivatives do not retain the solid state structure in solution. © 2003 Wiley Periodicals, Inc.

Corbin 5-Diphenylphosphino-2-hydroxy-1,3-xylyl-18-crown-5 has been synthesized from 5-bromo-2-hydroxy-18-crown-5 by reacting it in sequence at low temperature with n -butyl lithium and methyl diphenylphosphonite. The phosphorous donor properties of this phenol phosphine (OH derivative) and the corresponding phenoxide (O, derivative) have been studied in the presence and absence of alkali metal ions by determining the frequencies of the A1 ,(CO) bands of Ni(CO)3L complexes. For the OH and O, derivatives, the latter generated by addition of CsOH to the former, the ,(CO) bands are observed at 2067.6 and 2063.4 cm,1, respectively, providing the trend predicted by Hammett parameters for OH and O, substituents. Addition of Na+ or K+ to the OH derivative has little effect on this stretching frequency, but the former ion shifts the O, derivative band to 2067.7 cm,1 A solid state structure has been obtained of the OH derivative, and two independent molecules were found in the unit cell. Both have a single water molecule hydrogen bonded to two across-ring oxygen atoms and the phenol hydrogen. The crown ether ring has the usual gauche and anti arrangements for the C-C and CO bonds.

De Wall Abstract Previously established aggregate formation by alkyl-substituted crown ethers is considered with respect to the solid state structure of N,N,-didodecyldiaza-18-crown-6 (7), which was determined as its NaI complex (7,NaI,H2O). The complex forms a bilayer structure that was used as a benchmark for understanding the formation of aggregates and their inclusion volumes. Copyright © 2001 John Wiley & Sons, Ltd.
