Abstract
The present invention relates to various end use applications prepared from certain block copolymers. The block copolymers include one or more A or A′ blocks or B blocks plus one or more terminal M blocks. Each A and A′ is a block or segment comprising predominantly a polymerized alkenyl aromatic compound, each B is a block or segment comprising predominantly a polymerized conjugated alkadiene, and each M is a six membered anhydride ring and/or acid group. The anhydride rings are prepared by thermally decomposing adjacent units of (1-methyl-1-alkyl)alkyl acrylic esters such as t-butylmethylacrylate. A wide variety of polymers are disclosed having the stable anhydride rings in the polymer backbone. The invention relates specifically to various end uses prepared from the reaction product of such block copolymers with various reactive resins, reactive monomers and metal derivatives.
