DEFINITION

Classification: 525/277

Ethylenic reactant contains a carbonate group:

(under subclass 242) Subject matter wherein the ethylenic reactant contains a carbonate (-OO-) group, wherein the group may be linear, as in diallyl carbonate (CH2[end subscrpt]=CHCH2OO-CH2[end subscrpt]-CH=CH2) or cyclic, as in vinylene carbonate (CH=CH), etc. [figure]
