| titleOfInvention | PROCEDURE TO REDUCE THE CONTENT OF HYDROXYL GROUPS OF AN EPOXY RESIN. |
| abstract | Epoxy resins have their hydroxyl content reduced by reaction with an ester <FORM:1115578/C3/1> in which R1 is hydrogen or an alkyl, aryl, alkenyl or aralkyl radical R2 is a C1- 6 alkyl or alkenyl radical and R is a chlorine atom or a radical -COOR3 where R3 is a C1- 6 alkyl or alkenyl radical, or a radical -COR4 where R4 is an alkyl, alkenyl, aryl or aralkyl radical. Examples of suitable esters are ethyl acetoacetate and ethyl chloroacetate. Reaction may take place in the presence of a large excess of the ester the remainder of which is distilled from the treated epoxy resin at the end of the reaction. A basic catalyst, e.g. an alkoxide of an alkali or alkaline earth metal may be employed. Conventional hardness may be used to cure the modified resin. |
