Thermal effect on the microhardness of chitosan films
(2000)
In this communication we present the results obtained from a study on the effect of thermal treatments of chitosan films with different molecular weights, but with a similar acetilation degree, carried out by microhardness. ...
Selective crystallization of calcium salts by poly(acrylate)-grafted chitosan
(2005)
The biopolymer chitosan was chemically modified by grafting polyacrylamide or polyacrylic acid in a homogeneous aqueous phase using potassium persulfate (KPS) as redox initiator system in the presence of N,N-methylene-bi ...

(TAYLOR & FRANCIS INC, 2005)
The study on the toxicity of chitosan diethyl phosphate (ChDP), a controlled release insecticide, on the activities of butyrylcholinesterase (BuChE) and acetylicholinesterase (AChE) in rainbow trout exposed to this pesticide ...
Synthesis and characterization of chitosan alkyl carbamates
(WILEY-BLACKWELL, 2002)
The synthesis of chitosan methylcarbamate (ChMC) and ethylcarbamate (ChEC) is described by using a new methodology. Polymers with substitution degrees up to 63% for ChEC and 68.5% for ChMC were obtained. Derivatives with ...
Relationship between composition and structure in chitosan based hybrid films
(2000)
Chitosan/poly(aminopropylsiloxane) hybrid films were obtained by blending 3-(aminopropyl)siloxane oligomers (pAPS) with chitosan (CHI). The pAPS oligomers were prepared by the sol-gel method starting from 3-(aminopropyl) ...
