Production of crosslinked polymers using an oxazoline derivative

摘要

A process for producing a polymer having crosslinked structure, which comprises reacting a polymer having in the molecule a partial structure of the formula: <IMAGE> with an oxazoline derivative of the general formula: <IMAGE> wherein n is an integer of 1 to 4; R is an n-valent aromatic hydrocarbon radical; R1, R2, R3 and R4 are respectively the same or different hydrogen or alkyls having not more than 3 carbon atoms. The polymer shows an excellent adherence, and is of great industrial value as coatings, adhesives and molding materials with by far improved heat and solvent resistance.
