BLOCK POLYMER AND ANTISTATIC AGENT COMPRISING THE SAME

Title:

BLOCK POLYMER AND ANTISTATIC AGENT COMPRISING THE SAME

Document Type and Number:

WIPO Patent Application WO/2000/047652

Kind Code:

A1

Abstract:

A thermoplastic resin which comprises a resin, especially a polyolefin, and a block polymer comprising polyolefin blocks and hydrophilic polymer blocks and finely dispersed therein without the need of a compatibilizing agent and gives a molding having permanent antistatic properties even when it is molded under shear-free conditions and even when the block polymer amount is small, and which does not foul the molds or rollers during molding because of satisfactory compatibility and has excellent mechanical strength. The block polymer (A) is characterized by having a structure comprising blocks of a polyolefin (a) alternating with blocks of a hydrophilic polymer (b) having a volume resistivity of 10?5¿ to 10?11¿ $g(V).cm. An antistatic agent comprising the block polymer (A) is provided. The resin composition comprises the block polymer (A) and a thermoplastic resin (B). A molded article obtained by coating or printing a molding of a resin composition containing the block polymer (A) is further provided.
