PRODUCTION OF RADIATION-CURABLE ACRYLATE
The prodn. of radiation-curable acrylates (I) comprises (1) reacting hydroxy cpds. (II) with (meth)acrylic acid and (2) reacting the prods. with epoxide(s) (III); cpds. with one or more prim. or sec. amino gps. (IV) are added in or before stage (2), which is then continued until the acid no. of the...

Zusammenfassung: | The prodn. of radiation-curable acrylates (I) comprises (1) reacting hydroxy cpds. (II) with (meth)acrylic acid and (2) reacting the prods. with epoxide(s) (III); cpds. with one or more prim. or sec. amino gps. (IV) are added in or before stage (2), which is then continued until the acid no. of the mixt. has decreased by at least 3 mg KOH/g from its value at the time of addn. of (IV). Also claimed are acrylates (I) obtd. by this process. |
