Write the molecular formula and structural formula of BHA and BHT. What are thermoplastic polymers ? Write a note on aldol condensation. |
|
Answer» Solution :The MOLECULAR formula and structure of BHA and BHT are as follows : BHT i.e., Butylated Hydroxy Toluene  Formula : `((CH_(3))_(3)C)_(2)CH_(3)C_(6)H_(2)OH(C_(15)H_(24)O)` BHA i.e., Butylated Hydroxy Anisole.  Formula : `(CH_(3))_(3)C-C_(6)H_(3)-(OCH_(3))(OH)(C_(11)H_(16)O_(2))` Thermoplastic polymers : A thermoplastic (also called thermosoftening plastic) is a polymer which becomes pliable or moldable above a specific temperature and returns to a solid state upon cooling. Most thermoplastic polymers have a high molecular weight and polymer chains associate through intermolecular forces. The physical properties of a thermoplastic polymer change drastically without an ASSOCIATED PHASE change below its melting point and above its GLASS transition temperature. Example : PMMA i.e., poly methyl methacrylate, Nylon etc. |
