MATTE FINISHED PHENYLENE ETHER RESIN MOLDING

摘要

PURPOSE:To provide the titled resin molding having a matte appearance while retaining high impact resistance, by specifying the size, the distribution and the toluene swelling degree of rubberg polymer particles to be incorporated in a phenylene ether resin. CONSTITUTION:A phenylene ether resin consisting of a styrene polymer, rubbery polymer particles and a phenylene ether polymer is prepd. and molded. In this case, the rubbery polymer particles are controlled such that the sum of the sectional areas of the particles having a sectional area of 35mu<2> or above accounts for at least 5% of the sectional area of the molding according to electron-microscopic sectional photograph of slices obtd. from the resin molding by an ultraslicing method. Further, the relationship between the toluene swelling degree Y (times) and the average particle size X (mu) of the rubbery polymer particles in the molding is specified to satisfy the relationship and X is controlled to at least 5mu to obtain the titled phenylene ether resin molding.
