Abstract: Systems and methods are provided for using differential scanning calorimetry (DSC) to predict properties of fuel compositions, such as marine fuel oils. It has been discovered that various features of the data plots generated by DSC can be correlated with properties of interest for marine fuel oil compositions. The fuel composition properties that can be predicted based on DSC include, but are not limited to, density; micro carbon residue; pour point; and estimated cetane number (ECN). This can include prediction of ECN for resid-containing fuel compositions. Using DSC to predict ECN can reduce or minimize the number of resid-containing fuel oil samples that require testing using the limited availability equipment required for the IP 541 method.

Abstract: Provided are compositions comprising a propylene-based elastomer and a polyalphaolefin. The compositions may be particularly useful in elastic film compositions, and especially useful as elastic film layers in nonwoven laminates.

Abstract: Alternating crystalline-amorphous polyolefin based multiblock copolymer compositions and methods for producing these multiblock copolymer compositions are disclosed. Also disclosed is the use of these multiblock copolymer compositions as additives to high density polyethylene (HDPE) resins in order to form polymer blends having improved ductility and toughness over that of the HDPE resins while retaining high mechanical strength, and the use of these polymer blends in films.

Abstract: Plasticizers of indane and or tetralin esters and blends thereof with thermoplastic polymers, such as PVC, are disclosed.
