Fig. 2.
Schematic representation of a triblock and diblock copolymers chemical structures. Chemical structures and representations of the triblock copolymer P188 (PEO75–PPO30–PEO75) and diblocks of P188 (PEO75–PPO15) with differing end groups (–H and –C(CH3)3) where a and b represent the number of repeating PEO and PPO group respectively
