Is Polyoxymethylene a Cosmopolymer?

Abstract

AMONG interstellar polyatomic molecules, formaldehyde is now second only to ammonia in the spectroscopic certainty of its identification. Unlike some of these molecules, for example, ammonia and water, formaldehyde has been detected in many different regions of our Galaxy. This has led to the speculation that its occurrence is a general feature of the spiral arms of the Milky Way1. If this speculation is correct then the chemical reactions of this molecule under interstellar conditions are of considerable relevance to discussions of the chemical evolution of our Galaxy.
