Curable compositions incorporating anhydride-functional polymers derived from alkenyl succinic anhydride

摘要

A curable composition which comprises: (a) an anhydride-functional polymer obtained by polymerizing under free radical addition polymerization conditions, a monomer mixture comprising: (i) 20 to 75 weight percent of an alkenyl succinic anhydride having the structure: <IMAGE> wherein R1, R2 and R3 are each independently hydrogen or alkyl or substituted alkyl of 1 to about 30 carbons; and (ii) 25 to 80 weight percent of at least one (meth)acrylic monomer copolymerizable with the alkenyl succinic anhydride; and, optionally, (iii) 0 to 75 weight percent of at least one unsaturated monomer, other than a (meth)acrylic-monomer, which is copolymerizable with the anhydride and the (meth)acrylic monomer; and (b) a compound having an average of at least two functional groups per molecule which are reactive with anhydride groups.
