RECYCLING OF POLYACETAL FOR THE PRODUCTION OF POLYOXYMETHYLENE DIALKYL ETHERS
The present invention relates to a process for recycling polyacetal containing from 8 to 100,000 carbon atoms for the production of a produced polyoxymethylene dialkyl ether of formula R—(OCH2)n-OR′, in which R and R′ independently represent a methyl group or an ethyl group and n is an integer greater than or equal to 1, the process comprising a step of reacting an acid catalyst with a mixture comprising a polyacetal containing from 8 to 100 000 carbon atoms, a reactive polyoxymethylene dialkyl ether of formula R—(OCH2)k-OR′ in which k is an integer greater than or equal to 1, and optionally a solvent.

Low Emission Polyoxymethylene Composition
A polyoxymethylene polymer composition is disclosed containing a formaldehyde stabilizer package. The formaldehyde stabilizer package, which contains at least two emission control agents, dramatically and unexpectedly reduces formaldehyde emissions. The formaldehyde stabilizer package includes at least two emission control agents selected from the group of benzoguanamine compounds, a hydantoin, a substituted hydantoin, an amino acid, and an alkylene urea such as ethylene urea.
