The physical properties of novel thermoplastic random copolyesters [-(CH2)(n)-COO-/-(CH2)(n)-COO-](x) made of long (n=12) and medium (n=8) chain length -hydroxyfatty esters [HO-(CH2)(n)-COOCH3] derived from bio-based vegetable oil feedstock are described. Poly(-hydroxy tridecanoate/-hydroxy nonanoate) P(-Me13-/-Me9-) random copolyesters (M-n=11,000-18,500 g/mol) with varying molar ratios were examined by TGA, DSC, DMA and tensile analysis, and WAXD. For the whole range of P(-Me13-/-Me9-) compositions, the WAXD data indicated an orthorhombic polyethylene-like crystal packing. Their melting characteristics, determined by DSC, varied with composition suggesting an isomorphic cocrystallization behavior. TGA of the P(-Me13-/-Me9-)s indicated improved thermal stability determined by their molar compositions. The glass transition temperature, investigated by DMA, was also found to vary with composition. The crystallinities of P(-Me13-/-Me9-)s however, were unaffected by the composition. The stiffness (Young's modulus) of these materials was found to be related to their degrees of crystallinity. (c) 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40492.

The objective this work was to evaluate the degradation, fermentation and kinetics of passage rumen fluid en sheep fed diets containing different carbohydrate associated with the oil. Four rumen cannulated sheep were allotted in 4 x 4 latin square. The treatments consisted of diets with high neutral detergent soluble fiber and diets with high starch associated or not with 4,2% of oil. Incubation times were 3, 6, 12, 24, 48, 72, 96 and 120 hours and ruminal fluid was collected at 0, 2, 4, 6, 8, 10, 12, and 24 hours after feeding. Diets high neutral detergent fiber soluble resulted in greater degradation of dry matter, crude protein, neutral detergent fiber soluble and starch, and higher pH values, butyric acid production, dilution rate and ruminal recycling compared with diets high starch content. The inclusion of 4,2% oil the different carbohydrate sources had no influence on the fermentation kinetics and degradation of the fiber. High content of neutral detergent soluble fiber in the diet favors the ruminal fermentation compared to the high starch content.
