Abstract
Adhesive compositions are disclosed which include acrylates, their polymers, and free radical initiators. The compositions include a multi-functional alpha-alkoxyalkyl (meth)acrylate compound and a free radical initiator. The multi-functional alpha-alkoxyalkyl (meth)acrylate compound is the reaction product of: (a) a (meth)acrylic acid or a (meth)acrylate ester having a free carboxylic acid group; and (b) a compound including two or more 1-alkenyl ether groups and free of acetal and ketal groups, or a compound free of acetal and ketal groups and including one or more 1-alkenyl ether groups and a (meth)acrylate group. The compositions are easier and less expensive to prepare than conventional acrylate compositions and degrade when contacted with an acid medium or when heated. The compositions are useful in a wide range of applications and are compatible with conventional adhesive additives.
