Microproduct, medical microproduct, microwell array chip, microwell position detection plate, and micro resin pipette tip using the microproduct

摘要

A microproduct includes a resin composition including a polypropylene-based resin and a hydrogenated derivative of a block copolymer shown by the general formula "X-Y". The microproduct has micromachined features of a stamper precisely transferred by injection molding and a molded surface has a plurality of recesses and/or protrusions. In this case, X represents a polymer block immiscible with the polypropylene-based resin, and Y represents an elastomeric polymer block of a conjugated diene.
