摘要:
Polymers of olefinically unsaturated hydrocarbons suitable for use as intermediates for use in the manufacture of lubricating or fuel oil additives, are prepared from reactants in different phases by reacting the reactants in a reaction region defined by adjacent surfaces between which there is relative movement or in a thin film on a surface over which they move.

摘要:
On prépare du dithiophosphate de dihydrocarbyle ou du dithiocarbamate destinés à être utilisés comme additifs pour huile lubrifiante à partir de réactifs en différentes phases en faisant réagir les réactifs dans une zone de réaction définie par des surfaces adjacentes entre lesquelles il y a un mouvement relatif ou dans une couche mince sur une surface où se déplacent lesdits réactifs.
