TLDR
Sulfur olefins such as isobutylene which are soluble in hydrotreated oils are prepared by reacting a basic, aqueous alcoholic solution of sodium sulfide with an adduct formed by adding olefin to sulfur monochloride at low temperatures until the mole ratio of OE to SML is between 17-19 to 1 as discussed by the authors.Abstract:

Method for the preparation of olefin polysulfides, the products obtained and their utilization as lubricant additives
TL;DR: In this article, a method for the preparation of olefin polysulfides that can be used in particular as extreme pressure additives for lubricants is described, which includes reacting sulfur monochloride or dichloride with at least one mono-olefin containing 2 to 5 carbon atoms resulting in the formation of an adduct.

Preparation of sulfurized olefins
TL;DR: In this article, an inert gas is used as a purge during the formation of the olefin-sulfur halide adduct to prevent blackening of both the intermediate and the final product.

TL;DR: In this article, a sulfurized olefin of improved solubility in lubricating oil is made by reacting sulfur monochloride with a monoolefin (e.g. isobutylene) to form an adduct which is reacted with sodium sulfide, sodium hydrosulfide, sulfur and alkyl mercaptan (in an aqueous alcohol reaction medium).
