Abstract: The present invention relates to a crosslinkable composition comprising a polyol, a polyisocyanate crosslinker, a catalyst for catalysing the reaction between —OH groups of said polyol and —NCO groups of said crosslinker, a tertiary acid of formula RR?R?CCOOH (I), wherein each R, R? and R? group, independently, is an alkyl, alkenyl, aryl or aralkyl group containing at least one carbon atom, with the proviso that two or three of the R, R? and R? groups can be linked to form a ring structure and wherein the R, R? and/or R? groups can be substituted, and optionally, a complexing agent containing at least one —SH group, as well as its use for making coatings having improved application properties.

Abstract: A process for preparing crosslinkable oligomers comprising reacting at least one monomer having the structure: VHC?CHX, wherein more than 60% of such monomer or monomers has at least one crosslinkable functional moiety, and at least one monomer having the structure: WHC?CYZ at certain molar ratios and reaction conditions, in which V, X, W, and Z are predefined in the text. Curable coatings, sealants, and adhesives utilizing such crosslinkable oligomers and block, branched, star and comb-like graft crosslinkable copolymers derived from such crosslinkable oligomers are also disclosed.
