Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
44 words
A process for flame retarding cellulose acetate comprising: dissolving a water insoluble organic flame retardant in a solution of 20-80% water/80-20% monohydroxy alcohol having 1-4 carbon atoms, maintaining said solution at at least 90° F. while swelling and penetrating cellulose acetate with said solution.
Claim 2
Dependent Claim
44 words
A process for flame retarding cellulose acetate comprising: dissolving a water insoluble organic flame retardant in a solution of 20-80% water/80-20% monohydroxy alcohol having 1-4 carbon atoms, maintaining said solution at at least 90° F. while swelling and penetrating cellulose acetate with said solution.
Claim 3
Dependent Claim
25 words
