Abstract
A polycarbodiimide compound, which is a reaction product of a polycarbodiimide (a) having an isocyanate group at both ends, obtained by polymerizing at least one selected from aliphatic diisocyanate and alicyclic diisocyanate, and a polymer (b) that is a polymer of at least one selected from butadiene and isoprene or a hydrogenated product thereof and has a functional group capable of reacting with an isocyanate group.
