Abstract: The invention relates to a process for the curing of latently reactive, heat-curable compositions which do not harden at room temperature. The composition includes a polymer obtainable via reaction of certain compounds having two aldehyde groups with polyacrylate compounds having two or more acrylate groups, and also a compound which bears at least two thiol groups.

Abstract: A process for the manufacturing of a polymer with urethane groups can be performed. In a first alternative a five-membered cyclic monothiocarbonate, a compound with at least two amino groups selected from primary or secondary amino groups, and a compound with at least two function groups that react with a —SH group are reacted. In a second alternative a five-membered cyclic monothiocarbonate and a compound with at least one primary or secondary amino group, and at least one function group that reacts with an —SH group are reacted.

Abstract: The present invention relates to a process for preparing a polyurethane, comprising the reaction of a composition (Z1) at least comprising a compound (P1) reactive toward isocyanates, and a composition (Z2) at least comprising a polyisocyanate, wherein compound (P1) is obtained by the reaction of at least one polyepoxide with a compound (V1) selected from the group consisting of polyetheramines and polyetherols. The present invention further relates to polyurethanes obtained by such a process, and to the use of a polyurethane of the invention for coating of pipelines, as a “field joint” or of subsea equipment, for example “christmas trees”, for the offshore sector, and as a glass-syntactic polyurethane.

Abstract: Cured epoxy resins are widespread because of their excellent mechanical and chemical properties. Typically, epoxy resins based on bisphenol A diglycidyl ethers or bisphenol F diglycidyl ethers are used, but these are problematic for many sectors because of their effect on the endocrine system. The present invention relates to glycidyl ethers of limonene-based diols and/or polyols, and to curable epoxy resin compositions based thereon as alternatives to the bisphenol A diglycidyl ethers or bisphenol F diglycidyl ethers, or the epoxy resin compositions based thereon.
