分解速度も速く、また、成形も行いにくいためである。In the present invention, the cellulose acetate (A) means a compound in which at least 60% of the hydroxyl groups of cellulose are acetic acid esters, and it is particularly preferably applied to acetate, which is usually called diacetate and has some hydroxyl groups remaining. It For example, it is preferably applied to those in which 2 or more, preferably 2.2 to 2.9, of the three hydroxyl groups in the constitutional unit of cellulose are acetate. This is because when the number of the acetate groups is less than 2, the rate of biodegradation by itself is high and the molding is difficult.

Particularly, sulfonic acid and phosphonic acid are mixed with acetate. It is preferable in terms of affinity. It should be noted that esters that easily hydrolyze to these strong acids can also be used.

Amounts of 1-10% by weight are used. The preferred range is 0.
It is 1 to 5% by weight.
