Abstract
Low VOC emission polyoxymethylene and compositions and products that incorporate the polyoxymethylene are described. The polyoxymethylene is end capped with compound that can prevent degradation of the polymer and subsequent emission of VOC degradation products such as formaldehyde. The end-capped polyoxymethylene can include an inorganic linkage within the polymer backbone that is the reaction product of a terminal hydroxyl group of the polyoxymethylene and a hydrolyzable group of the compound. Also disclosed are products as may be formed from the low VOC emission polyoxymethylene.
