DITHIOPHOSPHATE COMPOSITION AND UTILITY IN RUBBER |
摘要 |
<p>The present invention relates to oligomeric or polymer dithiophosphate di- or poly-sulfides and their utility in rubbers. Another aspect of the invention is a method for making oligomeric or polymeric dithiophosphates by reacting phosphorous pentasulfide with a di- or polyol and a mono alcohol to produce a dithiophosphoric acid, and then oxidizing the dithiophosphoric acid with an oxidizing agent to produce an oligomeric or polymeric dithiophosphate.</p> |
