<p>Low-hygroscopicity low-birefringence resin compositions. One of the compositions is a resin composition (a) comprising the following polymer (A) and polymer (B) and/or (C). Another is a resin composition (b) comprising the following polymers (A), (B), and (H). Still another is a resin composition (c) comprising the following polymers (I) and (J), a diphenylsilicone (D), and a phenolic antioxidant (E). (A) A polymer comprising units of indene or an indene derivative represented by general formula (I). (B) Polystyrene or a derivative comprising a polystyrene derivative. (C) A polymer obtained from styrene or a styrene derivative and a copolymerizable monomer. (H) A graft polymer comprising the polymer (C) and bonded to a side chain thereof a polymer comprising units of indene or an indene derivative represented by general formula (I). (I) A polymer comprising the polymer (A) having a heterocyclic structure in a side chain thereof. (J) A polymer comprising the polymer (C) having a carboxyl group and/or a phenolic hydroxyl group in a side chain thereof.</p> |
