A production process of a rubber composition containing a modified conjugated diene-based polymer, which can provide a rubber composition in which processability is excellent, and a filling agent, when contained, has favorable dispersibility therein. The production process of the rubber composition includes: a first step of kneading a modified conjugated diene-based polymer that is obtained by polymerizing a monomer containing a conjugated diene compound and has at least one nitrogen-containing functional group selected from a primary amino group, a secondary amino group, a tertiary amino group and groups in which these amino groups have been converted into an onium group, and a basic compound having an acid dissociation constant of 8.0 or more; and a second step of kneading the kneaded product obtained in the first step and a cross-linking agent.

A moisture-curing polyurethane composition including: at least one isocyanate-functional polymer with a content of monomeric isophorone diisocyanate of below 0.5 weight-%, obtained from the reaction of isophorone diisocyanate and at least one polyol, and at least one aldimine of formula (I). The composition has a low toxicity, good shelf life stability and cures quickly to an elastic material of low surface tack and good mechanical properties, particularly in terms of high tensile strength and modulus of elasticity at high elongation. It enables coatings, sealants and adhesives with excellent stability under outdoor weathering conditions and high UV load. The aldimine of formula (I) allows to overcome the drawbacks caused by the removal of most of the monomeric isophorone diisocyanate in terms of cure speed, surface tackiness and final strength of such compositions.
