Claims
- 1. In a paper or paper-like product comprising layers laminated together by a plasticized sulfur adhesive, the improvement which comprises preparing the plasticized sulfur adhesive by heating to a temperature between 160.degree. C. and 220.degree. C. to obtain a molten, low viscosity adhesive.
- 2. A paper or paper-like product in accordance with claim 1 wherein the plasticized sulfur comprises a plasticizer selected from the group consisting of dicyclopentadiene, aliphatic polysulfides, aromatic polysulfides, or mixtures thereof.
- 3. A paper or paper-like product in accordance with claim 1 wherein the plasticized sulfur comprises sulfur, dicyclopentadiene, asbestos or glass fiber, and talc.
- 4. A paper or paper-like product in accordance with claim 1 wherein the plasticized sulfur is heated to a temperature between 175.degree. C. and 210.degree. C.
- 5. In a paper or paper-like product comprising layers laminated together by a plasticized sulfur adhesive, the improvement which comprises preparing the plasticized sulfur adhesive by (1) heating to a temperature between 160.degree. C. and 220.degree. C. to obtain a molten, low viscosity plasticized sulfur, and (2) cooling the hot plasticized sulfur in liquid form to a temperature below 150.degree. C. to obtain a liquid adhesive.
- 6. A paper or paper-like product in accordance with claim 5 wherein the plasticizer sulfur is heated to a temperature between 175.degree. C. and 210.degree. C.
- 7. A paper or paper-like product in accordance with claim 5 wherein the hot plasticized sulfur is cooled to a temperature below its normal melting point.
