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.
This result can he attributed to the two pumps simultaneously turned on during the process resulting in the core block polymer
containing some MMA monomers, and the shell block polymer
containing BA monomers.

, Cosmetic Composition Comprising it and Cosmetic Treatment Process," US Patent Application 20100021408A1, Jan.
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.
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.
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.
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).
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.
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 characterized by a combination of high tensile strength and rubber-like elasticity with the ease of thermoplastic or solution processing.
All ingredients are mixed simultaneously, resulting in a more random block polymer
The acrylate monomers with vinyl acetate form block polymers
that are not able to space the vinyl-acetate moieties.
