Phase separation in polymers is important for many technical applications but is difficult to predict theoretically. Recently, extensive experimental studies on the miscibility of polyolefins revealed that these systems display a wider variety of mixing behavior than their chemical similarity suggests. In order to predict phase diagrams of polyolefin blends from pure component properties, we ha...

A method of measuring the volume of the human dental pulp cavity is described. The crown of an extracted tooth is divided from its root. .After cleaning the pulp cavity, it is filled with an elastomer, and the fractured tooth surfaces repositioned before the elastomer sets. The tooth is corroded in acid to release the elastomer which is then weighed, and its volume calculated. The method has be...

This communication describes a highly efficient aziridinyl polyolefin cyclization catalyzed by InBr(3) to synthesize chiral terpenoid bearing a 3-amino group in the A ring; both good yields and excellent asymmetric induction were achieved.

A simple, one-pot approach to synthesize random semicrystalline/amorphous multiblock copolymers (12-17 blocks per chain on average) is demonstrated that takes advantage of acyclic diene metathesis (ADMET) polymerization of α,ω-divinyl-terminated telechelic polyolefins. This synthetic approach offers a generic, viable and economical route to polyolefin-based multiblock copolymers and may be exte...

Abstract. The use of polyolefin flexible foams with typical thicknesses between 1 and 3 mm produced by a physical foaming extrusion process is nowadays quite widespread in the packaging sector. Their high flexibility and closed-cell structure allows them to show good energy absorption properties under low loading conditions. Although the compressive response of these materials is well known, th...
