The temperature dependence of heat capacity of triple alternating copolymer ethylene—carbon monoxide—propylene with 23.4 mol.% of propane fragments was studied for the first time by adiabatic and dynamic calorimetry over the range of 6–480 K. The energy of copolymer combustion at 298.15 K was ...
1.Polarized green electroluminescence has been achieved at the peak wavelength of 550 nm fromalternate copolymerpoly (9,9-dioctylfluorene-alt-benzothiadiazole) (PFBT),which was synthesized by polycondensation.通过缩聚法合成了绿光9,9-二辛基聚芴-苯并噻二唑交替共聚物(PFBT)。 3)alternating copolymerization...
of PPNCl, this complex was found to be an active initiator for the copolymerization of PO and CA to afford poly(propylene cam- phorate) (Supplementary Figs S5–S8) with high Mn and narrow molecular weight distribution (entry 2). In agreement with previous observations41–43, we considered ...
particularly an α-olefin such as propylene. When the preferred polyketon terpolymers are employed as the major polymeric component of the blends of the invention, there will be within the terpolymer at least about 2 units incorporating a moiety of ethylene for each unit incorporating a moiety ...
Specifically, ethylene glycol, propylene glycol, pinacol, etc. may be used. The reaction may be performed by reflux using an organic solvent such as DMSO, DMF, CH2Cl2, THF, hexane, ethyl acetate, diethyl ether, benzene, toluene, xylene, etc. The reaction temperature may range from 30 to 20...
