Polyurethane product with sulfur-containing polyester polyol

A reaction system for forming a step-growth polymerized sulfur-containing polyester polyol, the reaction system comprising:

• at least one sulfur-containing component selected from the group of a sulfur-containing polyol and a sulfur-containing polycarboxylic acid, an amount of the at least one sulfur-containing component being from 1 wt % to 65 wt %, based on a total weight of the reaction system;
• at least one aromatic component selected from the group of an aromatic multi-functional ester, an aromatic multi-functional carboxylic acid, and an aromatic anhydride, an amount of the at least one aromatic component being from 1 wt % to 60 wt %, based on the total weight of the reaction system;
• at least one simple polyol that excludes sulfur and is different from the sulfur-containing polyol, an amount of the at least one simple polyol being from 0 wt % to 60 wt %, based on a total weight of the reaction system;
• and
• at least one polymerization catalyst, and
• an isocyanate component;
• wherein, the reaction system for forming the sulfur-containing polyester polyol having a sulfur content that is from 0.1 wt % to 1.3 wt %, based on a total weight of the reaction system.
