Ring-opening metathesis polymerization (ROMP) of norbornene with most catalysts produces a polymer with an atactic placement of the cyclopentylene rings, yet partial hydrogenation of this polymer is known to yield a crystalline product. We report her

Blown films of different types of polyethylenes, such as branched low-density polyethylene (LDPE) and linear high-density polyethylene (HDPE), are well known to tear easily along particular directions: along the film bubble's transverse direction for

‘Living’ ring-opening metathesis polymerization (ROMP) permits the synthesis of narrow-distribution homopolymers and well-defined block copolymers – provided no side reactions occur. However, acyclic metathesis between the chain end and double

While the crystal thickness and melting point in crystallizable homopolymers are kinetically controlled, an equilibrium degree of chain folding is predicted for crystalline−amorphous block copolymers. We demonstrate this effect in a series of diblo

Blown films of ethylene/methacrylic acid copolymers and ionomers can exhibit pronounced directional tear, meaning that a tear can propagate with much less resistance in a particular direction. However, films blown from the same resin can exhibit diff

Polycyclopentene with controllable molecular weight and polydispersity below 1.1 was obtained by ring-opening metathesis polymerization (ROMP) of cyclopentene at room temperature using a commercial...

Long-term completion performance is important for the economic development of any field. As fields are now developed in environments that are capital intensive and increasingly technically challenging, new technologies are required for optimization o

Model-Based Uncertainty Analysis (MBUA) is a method to evaluate reservoir performance using multiple 3D models. Experimental Design techniques are used to determine which 3D models are built (unique geologic models which are then simulated) based on
