hydrolysis

(hi-drol'i-sis) [? + lysis, dissolution]
Any reaction in which water is one of the reactants, more specifically the combination of water with a salt to produce an acid and a base, one of which is more dissociated than the other. It involves a chemical decomposition in which a substance is split into simpler compounds by the addition or the taking up of the elements of water. This kind of reaction occurs extremely frequently in life processes. The conversion of starch to maltose, of fat to glycerol and fatty acid, and of protein to amino acids are examples of hydrolysis, as are other reactions involved in digestion. A simple example is the reaction in which the hydrolysis of ethyl acetate yields acetic acid and ethyl alcohol: C2H5C2H3O2 + H2O = CH3COOH + C2H5OH. Usually such reactions are reversible; the reversed reaction is called esterification, condensation, or dehydration synthesis.

Hydrolytic degradation tests were carried out as follows: The PU chips were prepared by mixing the poly(ether ester) polyols with N3390 as the ratio of functional groups ([NCO]:[OH] = 1:1), respectively.
The use of the longer hydrophobic chain in the polyols is expected to result in a new class of polyurethanes with a very flexible, less polar soft segment with better elasticity at low temperatures, better hydrolytic stability (due to the lower ester content), and lower moisture pick-up in high-humidity environments such as automotive.
