ABSTRACT:
A composition comprising plasticized sulfur wherein the composition is prepared by steps including heating the plasticized sulfur to a temperature between 160.degree. C and 220.degree. C and then cooling the hot plasticized sulfur in liquid form below its normal melting point (freeze point) to thereby obtain a liquid, tacky, plasticized sulfur. Preferably the plasticized sulfur is brought to a temperature between about 170.degree. C and 210.degree. C and then cooled. The composition is useful as an adhesive and is useful as a binder in preparing conduit or pipe from laminated layers of paper-like material. The composition is also useful in preparing structures or structural members.
