The title compds. (I) were prepd. by reacting an acrylonitrile or its derivs. with a formaldehyde and/or acetaldehyde in the presence of acid catalyst. R and R1 are H, Cl, CN, C1-3 straight(or branched chain) alkyl independently; R2,R3,R4,1 and R5 are H, phenyl, C1-5 straight(or branched chain) alkyl independently; R6,R7,R8 are H or Me independently; When R2,R3,R4,R5,R6,R7, R8 and R are H, then R1 is not H. The mixing ration of acrylonitril and its derivs. is 0.25-4:1. (I) are useful as a reinforcing-acceleration agent.
