摘　　要：将胶原蛋白与两种去乙酰度(95%,85%)的壳聚糖分别配成不同质量比的HAc共混溶液,在28℃下测定了共混液的黏度,利用△b法则比较共混液中两种物质的相容性。结果表明在28℃的HAc溶液中,任何质量比的胶原蛋白和壳聚糖均相容,并且两者相容性不受壳聚糖去乙酰度的影响。The viscosity properties of collagen and chitosan and their blends at several composition （2/8,4/6,5/5,6/4, 8/2） have been studied in our research. The miscibility of this polymer system was investigated on the basis of the criteria Δb determined by the solution viscosity. Chitosan of different deacetylation degree （95%, 85%） have been compared for their miscibility with collagen. These experiments indicate that collagerdchitosan is miscible at any composition and different deacetylation degree （95%, 85%） in HAc at 28℃.
