New π-conjugated polymer with vinylene linkage, poly((10-hexyl-3,7-phenothiazine)-alt-(4-(4-butyl-phenyl)-3,5-diphenyl-4H-[1,2,4]triazole)-3,5-vinylene) (PTV-TAZ) was synthesized by the Heck coupling reaction. The photoluminescence (PL) maximum wave

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...

The hydrosilylation of olefins with allyldicholorosilane in the presence of chloroplatinic acid diluted with isopropanol gave allylalkyldichlorosilanes, retaining the allyl group. When the olefin was used in fivefold excess or more relative to allyld
