PURPOSE:To prevent minute powder of an abrasive from sticking to a synthetic resinous product so as to make the product look neat by mixing a specified useful substance with synthetic resin and regulating peculiar surface resistance of the abrasice below 10<10>OMEGA/cm. CONSTITUTION:One or more than two sorts of useful substances out of an antistatic agent (such as alkyl phosphoric acid, diethanol amino acid or the like) a surface active agent (such as dodecyl benzene sulfon acid or the like,) or a conductive filler (such as carbon black) are mixed with synthetic resin (such as non-saturated polyester resin). Then, synthetic resinous abrasive with peculiar surface resistance below 10<10>OMEGA/cm is obtained. |
