Abstract

NEW MATERIAL:A maleimido shown by the formula I (R and R' are H, halogen, or 1W4C alkyl; n and n' are 1W4).
EXAMPLE: 2-( 4'-Hydroxyphenyl )-2-( 4"-maleimido-phenyl ) propane shown by the formula II.
USE: Electrical insulating materials, heat-resistant adhesives, vulcanization accelerators coating compound, and especially raw materials for a resin required to have special functions utilizing OH groups and double bonds. Having an extremely large solubility in a low-boiling solvent, e.g., acetone, methylethyl ketone, etc. and good compatibility with a resin.
PROCESS: A maleamic acid shown by the formula III is reacted with a dehydrating agent, e.g., phosphorus pentoxide, polyphosphoric acid, a carboxylic acid anhydride to give a compound shown by the formula I by the dehydration through cyclization. The reaction is carried out in an organic solvent or in the presence of a catalyst and a tertiary a mine. After the reaction is over, good granules of the aimed compd. are precipitated by using a solvent, e.g., water.
