Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
107 words
A PROCES FOR ADHERING SURFACES MADE OF CELLULOSIC MATERIAL TOGETHER WHICH COMPRISES APPLYING A COMPOSITION CONSISTING OF AN AQUOUS SOLUTION OF A WATER-SOLUBLE DERIVATIVE OF AN ACROLEIN POLYMER OBTAINABLE BY REACTING THE POLYMER WITH A MEMBER OF THE GROUP CONSISTING OF SULFUR DIOXIDE, AN ALKALI METAL BISULFITE, AMMONIUM SULFITE, AMMONIUM BISULFITE AND SOIDUM HYDROXIDE TO AT LEAST ONE OF THE SURFACES TO BE BONDED, PRESSING THE SURFACES TOGETHER AND ALLOWING THE COMBINATION TO SET UNTIL THE ADHESIVE SOLUTION HAS SET HARD, SAID POLYMER OF ACROLEIN HAVING AN INTRINSIC VISCOSITY BETWEEN 0.5 DI./G. AND 3.5 DI./G. OBTAINED BY ADDITION POLYMERIZATION OF THE ACROLEIN THROUGH THE ETHYLENIC DOUBLE BOND.
