Coat structureMicrocapsuleThe rate of solvent evaporation, during the formation of ethylcellulose microcapsules employing polyisobutylene with theophylline ion-exchange resin as the core material, was found to affect the type of coat formed. The predominantly mononucleated microcapsules showed rapid release ...
The physical structure and properties of ethylcellulose (EC) powders of different molecular weights were examined. A molecular weight in the range of 20–144 kDa with a large polydispersity was determined. EC thermal analysis revealed a glass transition at ~130 °C and a melting temperature at ...

The mid-infrared spectra (3100−400 cm−1) of ethyldimethylphosphine CH3CH2P(CH3)2 dissolved in liquid xenon as a function of temperature (− 60 to − 100°C) have been recorded. Using the conformer pairs (transgauche) observed at 937947 and 10061016 cm−1, the enthalpy difference...
Synthesis of Surface-Responsive Composite Particles by Dehydration of Water-in-Oil Emulsions Organic composite particles were prepared by first emulsifying an aqueous sodium carboxymethyl cellulose (CMC) solution in a nonaqueous ethylcellulose (EC)... Chen Liang,Qingxia Liu,Zhenghe Xu 被引量: 0发表...
