(2005)The phosphazene polymers carrying phenoxycarboxylic acids {[NP(O-C 6H 4-CO 2H) 2] x[NP-(O 2C 12H 8)] 1-x} n [x = 0.2 (1a), 0.35 (1b), 0.5 (1c), 0.7 (1d), 0.85 (1e), x = 1(2)] and the chiral analogues {[NP(O-C 6H 4-CO 2H) ...
-
(1988)The polymerization of methyl methacrylate photosensitized by benzion methyl ether over a wide range of initiator absorbances was investigated. Both the polymerization rate and the polymer molecular weight distribution are ...
-
(John Wiley and Sons Inc., 2019)© 2018 Society of Plastics Engineers Polypropylene (PP) and polyamide-6 (PA6) nanocomposites containing thermally reduced graphene oxide (TRGO), obtained either at 600°C (TRGO 600 ) or 800°C (TRGO 800 ), were prepared by ...
-
(Blackwell Publishing Ltd, 2008)Alfvén/ion-cyclotron waves have been observed in several regions of the magnetosphere. Parametric decays of finite amplitude Alfvén/ion- cyclotron waves in the presence of He+ ions and a mixed population of thermal and hot ...
-
(Wiley-VCH Verlag, 1996)Grafting of polypropylene was carried out in both boiling xylene and decalin as solvent medium with itaconic acid (2-methylenesuccinic acid) as functional polar monomer using 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane ...
-
(Marcel Dekker Inc, 2000)Maleic acid-alt-styrene (MAaS) copolymer with number-average molecular weight M̄n = 2500 was used as a compatibilizer in blends of poly(ethylene oxide) (PEO) and poly(styrene) (PS). PEO with weight-average molecular weight ...
-
(Blackwell Publishing Ltd, 2009)It is well known that nonlinear electrostatic instabilities can be triggered in a plasma with streaming ion species in the presence of finite-amplitude Alfvén cyclotron waves. The instability occurs when the phase velocity ...
-

-
(2004)The reaction of [NPCl2]n first with 2,2′-dihydroxybiphenyl and K2CO3 or (R)-(+)-2,2′-dihydroxy-1,1′-binaphthyl and Cs2CO 3, and subsequently with HO-C6H4-CO 2Prn and Cs2CO3, gave the phosphazene copolymers {[NP(O2C12H8)] ...
-
(Blackwell Publishing Ltd, 2011)During the last decade, a number of studies have shown that turbulent processes in the plasma sheet are very important for the analysis of the formation of quasi-stable plasma sheet configurations. The existence of this ...
-
(2001)The synthesis of low-density polyethylene from ethylene as the only monomer feed has been investigated as an alternative route to branched polyethylene and to obtain new materials with different properties, avoiding the ...
-
(Wiley-VCH Verlag, 1997)This work reports the synthesis of a novel polymeric organic-inorganic hybrid. The inorganic component is a silica network obtained by controlled hydrolysis of tetraethyl orthosilicate via sol-gel process and the organic ...
-
(1995)This work reports a comparative study of the catalytic behaviour for a series of metallocenes derived from Ti, Zr, Hf and Nb, which after activation with methylaluminoxane can polymerize ethylene. Results show that the Zr ...
