Claims9
A method for preparing an aqueous cellulose composition comprising the following steps:
- a) mixing water and a cellulose compound selected from the group consisting of nitrocellulose, ethylcellulose and cellulose acetate butyrate in a ratio of from about 2 parts by weight water per part by weight cellulose compound to about 20 parts by weight water per part by weight cellulose compound, thereby forming a water-cellulose mixture;
- b) adding a glycol ether solvent to the water-cellulose mixture in a ratio of from about 2 parts by weight solvent to about 20 parts by weight solvent per part by weight cellulose compound present in the water-cellulose mixture thereby forming a water-cellulose solvent mixture;
- and
- c) mixing the water-cellulose solvent mixture thereby forming an aqueous cellulose solution.
An aqueous cellulose solution consisting essentially of a cellulose compound selected from the group consisting of nitrocellulose, ethylcellulose and cellulose acetate butyrate, water and glycol ether solvent in a ratio of from about 2 to about 20 parts by weight water and from about 2 to about 20 parts by weight solvent, per part by weight cellulose compound.
An aqueous cellulose solution consisting essentially of a cellulose compound selected from the group of nitrocellulose, ethylcellulose and cellulose acetate butyrate, water and glycol ether solvent in a ratio of from about 0.5 to about 4 parts by weight water and from about 1 to about 7 parts by weight solvent, per part by weight cellulose compound.
