研究了增塑剂的种类和用量对熔融加工热塑性淀粉的力学性能、热性能和吸水性能的影响。一般而言，一羟基醇和高分子量二醇不能使淀粉变性，而较短的二醇和山梨醇是有效的。增塑剂的量和类型没有明显影响加工样品的结晶度，但影响这些TPS的机械性能在两个相反的方式，即软化效果线索的非晶相的塑化和硬化由于一个antiplasticization效果。(c)2005爱思唯尔有限公司保留所有权利。
The effect of the type and amount of plasticizer on the mechanical, thermal and water-absorption properties of melt-processed thermoplastic starch was investigated. In general, monohydroxyl alcohols and high molecular weight glycols failed to plasticize starch, whereas shorter glycols and sorbitol were effective. The quantity and type of plasticizer did not affect appreciably the crystallinity of the processed samples, but influenced the mechanical properties of these TPS in two opposite ways, viz. a softening effect clue to the plasticizing of the amorphous phase and stiffening one due to an antiplasticization effect.
