The invention relates to a polypropylene based nucleating agent masterbatch and a preparation method thereof. The masterbatch is composed of, by weight, 0.1 to 60 wt. % of bis-2-hydroxyethylene terephthalate (BHETA) based nucleating agent, 40 to 99.9 wt. % parts of polypropylene. The present invention discloses a process for preparation of a polypropylene masterbatch by mixing polypropylene with a nucleating agent as represented in FIG. According to the invention, the prepared polypropylene masterbatch has the advantages of being a masterbatch which can be added in any grade of polypropylene, does not cause inhalation hazards while handling, is easy to handle and has improved dispersion in the base polypropylene.

The present disclosure describes an additive composition comprising: (a) an organometallic compound; (b) a nitrogen-containing compound; (c) an aryl peroxide; and (d) at least one solvent, wherein the organometallic compound to the nitrogen-containing compound to the aryl peroxide weight ratio is in a range of 7:0.5:0.5-9:1.5:1.5. The addition of additive composition not only synergistically improves the properties of the at least one fuel, such as, LPG for use as torch gas for cutting and welding application, but also reduces the consumption of both fuel and oxygen for cutting applications. The present disclosure is also directed towards a process for preparation of the fuel composition.
