T_g Confinement Effect of Random Copolymers of 4-tert-Butylstyrene and 4‑Acetoxystyrene with Different Compositions

, 2019
We observe that the Tg confinement effect of polymer films can saturate with polymer–substrate interaction. Thickness dependences of the glass transition temperature, Tg(h0), of random copolymer films of 4-tert-butylstyrene (TBS) and 4-acetoxystyrene (AS)

Influence of Strong Electron-Donor Monomers in Sequence-Controlled Polymerizations

, 2016
A series of styrenic monomers containing strong donor substituents (i.e., 4-methylstyrene, 4-acetoxystyrene, and 4-tert-butoxystyrene) were tested in sequence-controlled radical copolymerizations in the presence of acceptor comonomers (i.e., N ...

Terpolymerization of styrenic photoresist polymers: effect of RAFT polymerization on the compositional heterogeneity

, 2015
The heterogeneity of the chemical structure of photoresist polymers, both within and between the polymer chains, is believed to contribute to the phenomenon of line edge roughness in high-resolution lithography. The copolymerization and terpolymerization
