摘要:
Provided are: an alkoysilyl group-containing hydrogenated block copolymer produced by introducing an alkoxysilyl group into a hydrogenated block copolymer that is obtained by hydrogenating 90% or more of unsaturated bonds of a block copolymer that includes at least two polymer blocks [A] and at least one polymer block [B], the polymer block [A] including a repeating unit derived from an aromatic vinyl compound as a main component, the polymer block [B] including a repeating unit derived from a linear conjugated diene compound as a main component, and a ratio (wA:wB) of a weight fraction wA of the polymer block [A] in the block copolymer to a weight fraction wB of the polymer block [B] in the block copolymer being 20:80 to 60:40; a method for producing the same; a solar cell element encapsulating material; a sheet, a laminated sheet; a multilayer sheet; and a method for encapsulating a solar cell element. The alkoxysilyl group-containing hydrogenated block copolymer exhibits low hygroscopicity, a low water vapor permeability, transparency, weatherability, and flexibility, maintains excellent adhesion to glass even when exposed to a high-temperature/high-humidity environment for a long time, and can encapsulate a solar cell element without applying a special waterproof treatment.
