    摘要： The present invention provides a multicomponent composition that is substantially isocyanate-free and comprises a polycarbamate as a first component and a polyaldehyde or an acetal or hemiacetal thereof as a second component and further comprises an effective amount of a triggering agent such that the first and second components to cure at a temperature of from 0 C. to less than 80 C. to form a crosslinked polyurethane. The multicomponent composition forms an ambient temperature curable composition when all of its components are combined that has a pH of 7.0 or less. The present invention also provides processes crosslinked polyurethanes, and the crosslinked polyurethanes prepared by the processes.
