Synthesis of cyclic olefin polymers with high glass transition temperature and high transparency using tungsten-based catalyst system
Novel cyclic olefin polymers (COPs) derived from bulky cyclic olefins, tricyclodipentadiene (TCPD) and tricyclo[6.4.0.19,12]-tridec-10-ene (TTE), with high glass transition temperature (Tg), excellent thermal stability, and high transparency, have been synthesized by ring-opening metathesis polymerization (ROMP) and subsequent hydrogenation. ROMP of TCPD and TTE was carried out successfully wit...
متن کاملSynthesis of High Performance Cyclic Olefin Polymers (COPs) with Ester Group via Ring-Opening Metathesis Polymerization
Novel ester group functionalized cyclic olefin polymers (COPs) with high glass transition temperature, high transparency, good mechanical performance and excellent film forming ability have been achieved in this work via efficient ring-opening metathesis copolymerization of exo-1,4,4a,9,9a,10-hexahydro-9,10(1′,2′)-benzeno-l,4-methanoanthracene (HBM) and comonomers (5-norbornene-2-yl methylaceta...
متن کاملCyclic olefin polymers: innovative materials for high-density multiwell plates.
Extension of ultra-high-throughput experiment (UHTE) approaches to new assay methodologies is often limited by compromised data quality when samples are miniaturized. Overcoming this challenge requires attending to all components of an automated laboratory system contributing to assay variability. A key but often neglected source is the high-density multiwell platform or microtiter plate. Mater...
متن کاملOne-pot Synthesis of Pyrano[2,3-d]Pyrimidines using Nanocellulose-SbCl5 as a Highly Efficient and Bio-based Catalyst
The reaction of nano-cellulose and antimony pentachloridein dichloromethane gave nano-cellulose-SbCl5. Also nano-cellulose-SbCl5 has beencharacterized by energy dispersive X-ray spectroscopy(EDX), scanning electron microscopy (SEM)and Fourier transform infrared spectroscopy(FTIR).Nano-cellulose-SbCl5has been applied as a nano-catalyst for synthesis of pyrano[2,3-d]pyrimidines from the simple on...
متن کاملA highly efficient titanium-based olefin polymerisation catalyst with a monoanionic iminoimidazolidide pi-donor ancillary ligand.
The titanium complex Cp[1,3-(2',6'-Me2C6H3)2(CH2N)2C=N]Ti(CH2Ph)2, with a monoanionic eta 1-iminoimidazolidide ancillary ligand, is shown to be a highly efficient catalyst for olefin polymerisation when activated with the Lewis acid B(C6F5)3.
