Title:
HYPERBRANCHED POLYMERS AND LUBRICANT COMPOSITIONS COMPRISING THE SAME
Document Type and Number:
WIPO Patent Application WO/2022/077235
Kind Code:
A1
Abstract:
Provided is a hyperbranched polymer obtained by copolymerization of (a) 90 to 99.5 mole % of at least one alkyl (meth) acrylate; and (b) 0.5 to 10 mole % of at least one trithiocarbonate, wherein the trithiocarbonate includes at least one unsaturated functionality, and wherein the total mole % of the alkyl (meth) acrylate and the trithiocarbonate is 100 mole %. Provided are further directed to an additive composition and a lubricating oil composition.
