PROCESS FOR THE STABILIZATION OF MIXTURES of RECYCLED THERMOPLASTICS |
摘要 |
<p>Recycled mixtures of plastics, predominantly thermoplastics, as predominantly produced in the household, in commerce and also in industry and useful material collections, can be stabilized against thermooxidative degradation by adding a combination of a sterically hindered phenol with an organic phosphite or phosphonite and an inorganic compound from the series consisting of metal oxides, hydroxides and carbonates.</p> |
