Abstract
The present disclosure relates to a composition that includes a first copolymer having a first repeat unit and a second repeat unit as defined by Structure (I) where is a covalent bond, U1 is a molar fraction of the first repeat unit, (1−U1) is a molar fraction of the second repeat unit, 0≤n≤20, 0≤m≤20, 0<U1≤1.0, R is a linking group covalently linking the first copolymer to a second copolymer by the covalent bond, and R includes carbon, hydrogen, and sulfur.
