Structure, mechanics, electricity, calorifics, radialization and chemicalproperties are reviewed for polyperfluoroethylene-propylene and tetrafluoroethylene perfluoroalkyl vinyl ether copolymer.
For polysaccharide synthescs,ring open-ing polymerizatlon of 1,6-,1,4-,1,3-,and 1,2-anhydro sngars,and polycondensation of cya-noethylidene trityl ether sugars are described.
The bulk and solution photopolymerization of vinyl butyl ether were studied using diph-enyl-4-thiophenoxyphenyl sulfonium salt (DPTS) as photoinitiator.
In this paper ten lactonic crown ethers weresynthesized, of which seven were new compounds.Theirstructures were confirmed by EA,IR,1HNMR andMS analysis.
The Applications of Arylboronic Acid in biaryl synthesis,synthesis of diaryl ethers,synthesis of aromatic amines and catalytic addition reactions were summarized.
Four new materials,such as carbon suspension,sodium sulfonate of polyoxyethylene allyl glycidyl nonyl phenyl ether,vanillyl alcohol,vanillin,etc,in lead-acid storage batteries were reviewed.
