WebHydrolysis of polyesters. Simple esters are easily hydrolyzed by reaction with dilute acids or alkalis.Polyesters are attacked readily by alkalis, but much more slowly by dilute acids. Hydrolysis by water alone is so slow as to be completely unimportant. (You wouldn't expect your polyester fleece to fall to pieces if you went out in the rain!). WebDec 3, 2024 · Hydrolysis of alkoxysilanes produces silanol groups, which can spontaneously condense to form siloxane oligomers. By performing the partial hydrolysis reaction at low temperatures, such as temperatures between 0° C. to 20° C., for a period of time less than or equal to 120 minutes, the amount of spontaneous condensation may be minimized.
