ABSTRACT:
The present invention relates to a process for the preparation of N-(hydroxyphenyl)maleamic acid and various dimers and oligomers thereof. The process is characterized by heating, in the absence of any solvent, N-(hydroxyphenyl)maleamic acid at a temperature ranging from about 150.degree. to about 250.degree. C. in the presence of an acid catalyst. This unique process avoids the need to recover expensive highly polar solvents. The present invention also relates to use of these maleimide containing compounds in rubber. The use of the blend of hydroxyphenyl maleimide and the various dimers and low molecular weight oligomers impart superior properties to rubber when compared to the use of hydroxyphenyl maleimide alone in rubber.
