PROCEDURE FOR PRODUCING SOLUBLE CELLULOSE DERIVATIVES |
摘要 |
<p>The present invention concerns a procedure for producing cellulose carbonate from cellulose and urea. To avoid alkali treatment of the cellulose used as starting material with a view to decreasing the degree of polymerisation of the cellulose, the cellulose in web form is exposed to a radiation dose of preferably 0.5 to 10 Mrad from a radiation source, whereafter the cellulose is reacted with urea at elevated temperature.</p> |
