Full Text	FIELD OF INVENITION This invention relates to a rodent repellent, anti-fungal, anti-termite composition and a process for the preparation thereof. Rodent repellent, anti-fungal, anti-termite composition is used for stopping growth of termites, fungi and the rodents from damaging the laminates laid in the godowns and food storage. It is also used for water/moisture proofing in the godowns, food storages and other packages. PRIOR ART Rodent repellent, anti-fungal PVC (polyvinyl chloride) compositions are not as such known in the prior art for stopping the entry of the rodents in the godowns/storage and to prevent growth of fungi and termites -Therefore, around 45% food grain material in India is wasted during the storage period. OBJECTS OF PRESENT INVENTION The main object of this invention is to propose a rodent repellent, antifungal and anti-termite composition to stop the entry of the rodents in to the godowns/storage for food grains and to prevent growth of fungi and termites on the grains as well as packaging materials. Another object of this invention is to propose a process for preparation of rodent repellent, anti-fungal and anti-termite composition. DESCRIPTION OF INVENTION In accordance with this invention there is provided a process for preparing of rodent repellent, anti-fungal and anti-termite composition comprises of 100 parts resin preferably poly-vinyl chloride (PVC) into a ribbon blender maintained at temperature of 80-90° C and adding 1-10 phr stabilizer and the step of blending is done for 3-5 minutes. 40-80 phr plasticizer is added into said blender and mixing is done till a free flow powder is obtained.
