Title:
ACRYLIC RESIDUE-CONTAINING MALEIMIDE DERIVATIVE
Document Type and Number:
Japanese Patent JP3183973
Kind Code:
B2
Abstract:
PURPOSE: To obtain a novel maleimide derivative containing an acrylic-or methacrylic residue which is useful as a heat stabilizer in an acrylic adhesive for structures.
CONSTITUTION: The novel compound is a maleimide derivative of formula I [wherein R is H or CH3; and A is 5-10C cycloalkyl or 6-12C aryl wherein acryloxy residue[-OCOC(R)=CH2] is at the ortho, meta or para positionl, e.g. N-(4-phenyl methacrylate) maleimide. The compound of formula I is obtained by allowing a halogenated acryloyl of formula II (wherein Alg is a halogen such as Cl) to react with an N-substituted maleimide of formula III. Here, this reaction is preferably carried out in the presence of a type 3A molecular sieve comprising a hydrated aluminosilicate of an alkali-or alkali earth metal or a zeolite.
