Abstract: Disclosed herein is a copolymer solution, comprising: a first polymer chain, comprising one or more capped ends formed by reacting a polyester diol with an anhydride; a second polymer chain, comprising two or more repeating units of the first polymer chain propagated from the one or more capped ends; and a third polymer chain, comprising one or more repeating units of the first polymer chain having at least one branched chain propagating from the one or more capped ends; wherein the copolymer solution has a viscosity of from 50 cP to 1000 cP at room temperature; and wherein each of the first polymer chain, the second polymer chain, and the third polymer chain is independently capable of crosslinking with the first polymer chain, the second polymer chain, the third polymer chain, or a combination thereof. Also disclosed herein are methods of making the same.
