BIODEGRADABLE FILMS ON 3-POLYHYDROXYBUTYRATE/3-POLYHYDROXY- -HEXANOATE COPOLYMER BASE |
摘要 |
<p>FIELD: organic chemistry. SUBSTANCE: invention relates to a film involving biodegradable copolymer where copolymer has at least two statistically repeating monomeric links where the first link has the formula: <EMI ID=0.459 HE=15 WI=33 TI=CHI> and the second link has the formula: <EMI ID=0.460 HE=15 WI=33 TI=CHI> and at least 50% of links have the formula of the first link. Also, invention relates to an absorbing article involving the upper liquid-permeable coating, bottom liquid-nonpermeable biodegradable coating containing the above indicated film and the central absorbing layer arranged between the upper and bottom coating. Invention ensures to obtain the sanitary single article consisting of a film that comprises a biodegradable poly-3-hydroxybutyrate. EFFECT: improved quality of biodegradable film. 7 cl, 11 ex</p> |
