A MULTI-PANE THERMALLY INSULATING CONSTRUCTION AND METHOD FOR MAKING SAME ABSTRACT OF THE DISCLOSURE A multi-pane thermally insulating construction having at least one chamber provided by argon gas impermeable transparent panes which are sealed at the edges with a solid elastomer of a cured polymer composition having very low impermeability to argon gas, the polymer composition containing from 90 mole percent to 25 mole percent of a thioether mercaptan terminated disulfide polymer of the forumula HS(RSS)mR'SH wherein R is -C2 H4 -O-CH2-O-C2H4-, R' is an alkyl thioether of from 4 to 20 carbon atoms and the value of m is such that the thi.oether mercaptan terminated disulfide polymer has a molecular weight of between about 1000 to about 4000. Methods of utilizing the polymer composition to seal thermally insulating constructions are also disclosed.
