Abstract
Terminally functionalized silicone triblock copolymers prepared using protected functionalized initiators and processes for preparing the same. The silicone triblock copolymers includes protected, functionalized silicone diene and/or alkenylsubstituted aromatic copolymers. The protected functionalized copolymers can be optionally deprotected to afford functionalized silicone diene and/or alkenylsubstituted aromatic copolymers.
