A high-chi diblock copolymer (BCP) for self-assembly comprises a first block comprising repeat units of trimethylsilyl styrene (TMSS) and styrene, and a second block comprising an aliphatic carbonate repeat unit. The blocks are linked together by a fluorinated junction group L′ in which none of the fluorines of L′ are covalently bound to an atomic center of the polymer backbone. A top-coat free film layer comprising the BCP, which is disposed on an underlayer and in contact with an atmosphere, is capable of forming a perpendicularly oriented lamellar domain pattern on an underlayer that is preferential or non-preferential to the domains of the block copolymer. The domain pattern can be selectively etched to provide a relief pattern comprising a remaining domain. The relief pattern having good critical dimensional uniformity compared to an otherwise identical polymer lacking the silicon.

The present invention provides a conductive polymer composite including: (A) a π-conjugated polymer, and (B) a dopant polymer which contains a repeating unit “a” shown by the following general formula (1) and has a weight-average molecular weight in the range of 1,000 to 500,000. There can be provided a conductive polymer composite that has excellent filterability and film-formability by spin coating, and also can form a conductive film having high transparency and flatness when the film is formed therefrom.
