Abstract
The present disclosure provides an adhesive made from a reaction product of: (a) one or more polymerizable monomer selected from the group consisting of n-C6 to n-C14 (meth)acrylates derived at least in part from non-petroleum resources; (b) an initiator; (c) a polymeric stabilizer, wherein the reaction occurs in water to yield a microsphere adhesive. The microsphere adhesive can be formulated into a pressure sensitive adhesive composition that can be applied to various substrates such as paper and polymeric film to produce repositionable adhesive coated articles such as tapes, notes, flags, easels, and the like.
