摘要： Stable NCO prepolymers are produced from polyisocyanates having a melting point greater than 70.degree.C, preferably, naphthalene diisocyanate, having advantageous physical properties. An important feature of the process of the present invention is the rapid cooling of the prepolymer. The process of the present invention may be carri ed out on a continuous or batch basis. The prepolymers of the present invention are particularly suitable for the production of cast polyurethane elastomers.

摘要： PROBLEM TO BE SOLVED: To provide a material system exhibiting improved characteristics in the temperature dependency of material characteristics particularly a storage modulus G', a loss tangent tanδ and a loss modulus G", while retaining good other characteristics. SOLUTION: Provided is a cast elastomer which is composed of a reaction product of an isocyanate prepolymer produced by reacting a high-temperature melting point polyisocyanate with a polyol, a chain extender, and optional auxiliaries and additives, wherein the molar ratio of isocyanate groups over Zerewitinoff active groups in the total components, is in the range of about 1.04 to about 1.25, and the ratio of a storage modulus G' measured at -30°C over that measured at 110°C, is in the range of about 0.8 to about 2.0.

摘要： An isocyanate (NCO)-terminated prepolymer is prepared by reacting polycarbonate polyol(s) with a stoichiometric excess of 4,4'-diphenylmethane diisocyanate. The polycarbonate polyol is treated by a short-path or thin-film distillation before being reacted with the 4,4'-diphenylmethane diisocyanate so that the hydroxyl value of the polycarbonate polyol is reduced by at least 1.5 hydroxyl value units. An independent claim is also included for a process for the preparation of polyurethanes comprising reacting at least polyisocyanate component comprising the NCO-terminated prepolymer produced by the inventive process with at least one isocyanate-reactive component.
