POLYMER COMPOSITIONS FOR THE PRODUCTION OF ARTICLES OF BIODEGRADABLE PLASTICS MATERIAL AND METHOD FOR THEIR PREPARATION |
摘要 |
Polymer compositions useful for the production of articles of biodegradable plastics material with improved biodegradability include destructed starch and a polymer selected from the group consisting of ethylene-vinyl alcohol, polyvinyl alcohol and mixtures thereof wherein at least a portion of the said polymer is modified by the substitution of from 0.1 to 5 molar % of the functional alcohol groups in the polymer chain by X groups in which X is an oxo or an alkyl carbonyl group in which the alkyl group contains from 1 to 4 carbon atoms. |
