The present disclosure provides an effective and efficient process for the preparation of a dry chlorinated polyvinyl chloride (CPVC), comprising introducing chlorine gas into slurry of polyvinyl chloride in water to obtain a reaction mixture; irradiating the reaction mixture to obtain a product mixture comprising CPVC and water solution including unreacted chlorine gas and hydrogen chloride; filtering the product mixture to obtain a first mass; adding water to the first mass for extracting unreacted chlorine gas and hydrogen chloride to obtain an aqueous suspension, and filtering the aqueous suspension to obtain a second mass; passing nitrogen through the second mass to extract residual water solution to leave behind a third mass; and agitating the third mass in a high-speed mixer together with a neutralizing agent, and optionally with a stabilizer and a processing additive to obtain dry thermally stable CPVC with thermal stability in the range of 1000 seconds to 1500 seconds.

Process for the preparation of dry chlorinated polyvinyl chloride

The present disclosure relates to a process for the halogenation of hydrocarbon. In accordance with the process of the present disclosure a hydrocarbon and a halogen is introduced in a reaction vessel. Light having wavelength in the range of 390 to 780 nm is then passed into the reaction vessel for a time period of 2 to 12 hrs. to obtain a halogenated hydrocarbon. The hydrocarbon is agitated before or after the introduction of the halogen in to the reaction vessel.

Halogenation of hydrocarbons

The present disclosure provides a process for separating oxygenates present in an aromatic hydrocarbon stream to obtain an oxygenates-free aromatic hydrocarbon stream. The process involves selectively removing oxygenates from the aromatic hydrocarbon stream by passing said stream through at least one zeolite based adsorbing material.

The present invention relates to a non-cryogenic process for the large scale synthesis of disentangled ultra high molecular weight polyethylene (DUHMWPE) polymers. The process comprises of the following steps: with a hydrocarbon solvent containing poly-methyl aluminoxane (P-MAO) co-catalyst in a vessel under stirring before polymerization or directly in the polymerization vessel at a temperature ranging between 25&#xb0; C. and 29&#xb0; C. under a dry Nitrogen atmosphere; and lower concentration of co-catalyst resulting in the associated benefits as described earlier in the claims and descriptions.
