Solid polysulfide containing hot melt sealants, adhesives and the like

Solvent free hot-melt compositions adapted to be extruded for use as sealants, adhesives, caulking compounds, expansion joints and the like consisting essentially of an unreacted mechanical mixture of 100 parts by weight of a polymerized elastomeric polysulfide compound having a molecular weight above about 15,000;

• with from about 1 to 400 parts by weight of tackifying resin selected from the group consisting of terpene resins, polyterpene resins, phenolic resins, hydrogenated rosin, hydrocarbon resins, and mixtures thereof;
• from about 15 to 600 parts by weight of plasticizer selected from the group consisting of polybutenes, polyisobutylenes, phosphate esters, dibutyl phthalate, straight chain aliphatic acid esters, parafine oils, coal tars, asphalts, chlorinated polyphenyl, chlorinated biphenyl and mixtures thereof;
• from about 0.5 to 60 parts by weight of adhesion promoter selected from the group consisting of epoxy resins organic silanes, urethane polyesters and polyethers, ethylene vinyl acetate, phenolic resins and non-reacting mixtures thereof;
• and from about 5 to 1000 parts of inert filler material;
• said composition being readily extrudable at temperatures above about 150.degree. while hardening upon cooling without undergoing chemical change, and having a hardness of about 5 to 95 on a Shore A Durometer at room temperature.
