<p>The present invention intends to provide a pressure-sensitive adhesive sheet for dicing which inhibits the generation of fibrous scraps and has good expandability. The present invention relates to a pressure-sensitive adhesive sheet for dicing, which includes a base material and at least one pressure-sensitive adhesive layer disposed on at least one surface the base material, in which the base material contains a polymer having a random copolymer block, and the random copolymer block contains a block (I) containing, as a main constitutional unit, a constitutional unit represented by the following structural formula (A):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ -(CH 2 -CH 2 -CH 2 -CH 2 )-€ƒ€ƒ€ƒ€ƒ€ƒ(A)
and a block (II) containing, as a main constitutional unit, a constitutional unit represented by the following structural formula (B):</p> |
