5B that most of block polymer would form simple sphere-like micelles with different addition amount of DMF, but some of them have irregular geometry and are not uniform.

It is comprised of a first layer comprised of a mixture of a homopolymer or copolymer of polypropylene and a block polymer of a vinyl aromatic monomer and a conjugated diene, a partially hydrogenated derivative, or a selectively hydrogenated derivative to which has been grafted a unsaturated carboxylic reagent.
The phase behavior of the synthetic block polymer for diblock copolymers (A-B) and triblock copolymers (A-B-A, A-B-C) had been extensively investigated [1-3].
These rheological data also indicate that SBC based compounds can be optimized for rheological properties, depending on the relative molecular weight differences between the block polymer and ethylene copolymer.
Although Zhao and coworkers have reported the light-controllable block polymer micelles (20), to the best of our knowledge, there are few studies focusing on the self-assembled particles of photosensitive graft polymers containing cinnamate groups (21), (22).
As a consequence, only a fraction of the block polymer would have the A-B-A structure, while other macromolecules would have the A-B or A morphology.
However, in the articles devoted to the grafting on [SiO.sub.2] nanoparticles, little attention was paid to [SiO.sub.2]/polystyrene(PS)-b-polymethacry-loxypropyltrimethoxysilane(PMPTS) hybrid nanoparticles via surface-initiated ATRP (SI-ATRP), especially characteristics of the PS-b-PMPTS block polymer and the morphology of the hybrid nanoparticles (it should be the crucial point which designs the roughness of micrometric particles).
These block polymer structures are said to be characterized by a combination of high tensile strength and rubber-like elasticity with the ease of thermoplastic or solution processing.
