Polyesters made from cyclic lactones or from hydroxyl alkyl carboxylic (e.g. HO (CH2)5COOH acids have identical chemical structures but with significantly different molecular weights and molecular weight distribution. Which of the following statements about the polymers is correct? (Choose from the following four possibilities)

		Chemical stability of the ester bonds is different because of differences in molecular weight.
		The polymers most likely have the same mechanical and solution properties.
		The solution and mechanical properties are most likely different for each polymer.
		The mechanism of non-covalent secondary bond interactions by the polymer ester groups is different in both polymer groups.
