The present invention relates to new bi-functional and polyfunctional bis-dioxolanes and bis-dioxanes. The present inventors have established that the bis-dioxolanes and bis-dioxanes of the invention are highly advantageous as building blocks, cross-linking and/or coupling agents in polymer engineering. They can be derived from biomass sources in a highly efficient manner. The production of the present bis-dioxolanes and bis-dioxanes from biomass has the particular advantage that it facilitates the introduction of desired functionality in a highly flexible manner. Hence, the present invention provides novel bi- or polyfunctional bis-dioxolanes and bis-dioxanes, their production from renewable (biomass) sources, as well as their use in the engineering of polymers.

Bis-diox(ol)ane compounds

The present invention relates to a powder paint composition comprising at least (a) a thermosetting polymer having functional groups capable of reacting with &#x3b2;-hydroxyalkylamide units (b) a compound comprising &#x3b2;-hydroxyalkylamide units and (c) a deceleration agent, capable of reversibly blocking the functional groups of polymer (a). The deceleration agent is present in an amount sufficient to block at least 9% of the total amount of functional groups of polymer (a). The present invention relates also to the use of a specific amine compound as a deceleration agent in a powder paint composition.
