One-pot synthesis of semicrystalline/amorphous multiblock copolymers via divinyl-terminated telechelic polyolefins.
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...
متن کاملEfficient synthesis of trifluoromethylated cyclopentadienes/fulvenes/norbornenes from divinyl ketones.
The synthetic methods of trifluoromethylated cyclopentadienes/fulvenes/norbornenes have been developed using 3-CF3-1,4-dien-3-ols as the synthons, which can be easily prepared by the regiospecific 1,2-addition of the Ruppert–Prakash reagent (TMSCF3) to divinyl ketones. All the reactions are carried out under mild, metal-free conditions to afford the corresponding products in high to excellent y...
متن کاملFirst synthesis of naphthalene annulated oxepins
Highly condensed oxepins have been prepared in good yields from their corresponding diols by etherification using p-toluenesulfonic acid. Their intriguing twisted structures were unambiguously determined by X-ray crystallography. Substitution effects of a novel highly aromatic naphthalene annulated oxepin indicate that structural and conjugative effects have an influence on the optoelectronic p...
متن کاملSynthesis of blood compatible polyamide block copolymers.
Blood compatibility of polyamides has been improved by introducing amido-amine groups in polymer backbone. Polyamide block-copolymer are synthesized by reacting amine end-capped polyamides with N,N'-methylene-bisacrylamide. Polyamide block-copolymers, thus produced found to have the ability of absorbing heparin. Heparinized polyamide block-copolymers have shown significant improvement in blood ...
متن کاملSolid phase synthesis of biohybrid block copolymers.
A new versatile route to synthesise biohybrid block copolymers is presented in which an amine terminated polymer is attached to an aldehyde functionalised resin, from which in subsequent steps the desired peptide can be grown using standard procedures.
