Immunoelectrophoresis on Cellulose Acetate Membranes
American Journal of Clinical Pathology, 1972An immunoelectrophoretic technic that uses a standard cellulose acetate membrane as supporting medium is described. Measured volumes of sample and antiserum are applied directly to the membrane surface. Immunodiffusion takes place between two contacting glass plates and within plastic wrapping.

Transitions of Cellulose Acetate
Journal of Macromolecular Science: Part A - Chemistry, 1983Abstract The transitions of cellulose acetate (40% acetyl) have been studied by differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). Two distinct transitions, one at 63°C and the other at 218°C, have been observed. An exothermic peak at 234°C is attributed to crystallization and is analyzed by the Kissinger and the Ozawa ...

Immunoisotachophoresis on cellulose acetate films
Bulletin of Experimental Biology and Medicine, 1978Acetate-cellulose strips of "Cellogel" type have been shown to be a suitable maintenance medium for performance of isotachophoresis. For immuno-isotachophoresis antigen (from 0.5 to 20 microliter) is applied to a strip of acetate-cellulose film. 1--2 microliter of ampholine solution is placed in front of the antigen zone.

Hydroxybutenyl cellulose acetates
Fibre Chemistry, 1997The effect of the conditions of acetylation of hydroxybutenyl cellulose and vulcanization of the acetates obtained on the physicomechanical properties and structure of films and cloth was investigated. X-ray structural analysis and electron microscopy revealed the structural characteristics of the products of HBC — HBCA chemical transformations and the

Journal of Applied Polymer Science, 1961
The possibility of grafting and polymerizing unsaturated monomers, styrene chiefly, on cellulose acetates of different acetyl contents after introduction of an unsaturated group in the cellulosic ester was studied. This group was introduced by further esterification with unsaturated anhydrides (maleic and crotonic) or by etherification with ...
