Abstract
Abstract A composition of matter comprising a thermoplastic resin and, as an antistatic agent, N,N''-substituted xylylene diamine. Because of a stability of the antistatic agent used, no fuming phenomenon occurs during fabrication of the composition, and the resulting fabricated articles have good antistatic properties and are free from surface clouding.
