Thermoplastic or elastomeric compositions based on esters of a starchy material and method for preparing such compositions
Abstract:
A thermoplastic or elastomeric composition, is characterized in that: a) it exhibits a degree of biodegradability of less than 50%, preferably less than 30%, and b) it contains at least 0.5% and at most 99.95% by weight of an ester of a starchy material, which has a degree of ester substitution (DS) of between 1.6 and 3, and at least 0.05% by weight and at most 99.5% by weight of a polymer other than starch.
Abstract(Chinese):

热塑性或弹性体组合物的特征在于：a）其显示的生物降解程度小于50％，优选小于30％，和b）其含有至少0.5％和至多99.95％重量的酯 的淀粉质材料，其具有1.6至3重量％的酯取代度（DS），以及除淀粉之外的至少0.05重量％和至多99.5重量％的聚合物。
