Abstract
A thermoplastic resin composition having deodorizing properties, which is obtained by adding to a thermoplastic resin from 0.5 to 100% by weight of fine powders of ferrous sulfate having a total content of crystal water and free water of not more than 20% by weight or fine powders of aluminum sulfate, potassium aluminum sulfate, sodium aluminum sulfate or zinc sulfate having a total content of crystal water and free water of not more than 5% by weight, and kneading the mixture and/or molding the mixture. The composition can be processed at high temperatures and does not undergo color change with time.
Claims9
A thermoplastic resin composition having deodorizing properties, which comprises a polyolefin resin and from 10 to 100% by weight, based on the resin, of a deodorizer selected from the group consisting of fine powders of ferrous sulfate, aluminum sulfate, potassium aluminum sulfate, sodium aluminum sulfate, and zinc sulfate, with the provisions that the ferrous sulfate has a total content of crystal water and free water of not more tan 20%, and the aluminum sulfate, potassium aluminum sulfate, sodium aluminum sulfate, and zinc sulfate each have a total content of crystal water and free water of not more than 5% by weight.
A thermoplastic resin molded product having deodorizing properties, which is obtained from a thermoplastic resin composition comprising a polyolefin resin and from 10 to 100% by weight, based on the resin, of a deodorizer selected from the group consisting of fine powders of ferrous sulfate, aluminum sulfate, potassium aluminum sulfate, sodium aluminum sulfate, and zinc sulfate, with the provisions that the ferrous sulfate has a total content of crystal water and free water of not more than 20%, and the aluminum sulfate, postassium aluminum sulfate, sodium aluminum sulfate, and zinc sulfate each have a total content of crystal water and free water of not more than 5% by weight.
