BACKGROUND :- These resins are Thermoplastic Polymers manufactured by copolymerization of cyclic terpene hydrocarbon (like Pinene‚ Carene etc.) and phenol. There are various grades of this resin with softening points ranging from 70 - 110C. These resins are compatible with Natural and Synthetic Rubbers‚ Rosin‚ Alkyd resins‚ and most of the plasticizers and waxes. Applications are in the manufacture of tubes‚ tyres‚ gaskets‚ cables‚ pressure sensitive adhesives‚ hot melt adhesives‚ surgical

INTRODUCTION: Carboxylic acids are organic acids characterized by the presence of a carboxyl group‚ -COOH. This acid acts as a weak acid‚ which can react with a strong base. Carboxylic acids form hydrogen bonds with many water molecules and are more soluble with one to four carbon atoms. Also‚ it may have an R group that consist of hydrogen or an alkyl group that changes its water solubility. Carboxylic acids with low molecular weight have odor at room temperature and higher molecular weight

Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4. Valence electrons: 4 Property: Non-metal Abundance:- Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon:- The Covalent
