Process for the preparation of anion exchange membrane

A process for the preparation of inter-polymer anion exchange membrane wherein the said process comprising the steps of:

• a) preparing an inter-polymer film of p-methylstyrene-co-divinyl benzene ((p-MS-co-DVB)/binder by adding p-methylstyrene as monomer, divinylbenzene as crosslinker, benzoyl peroxide as radical initiator either neat or into a solution of PVC in a solvent under stirring at temperature ranging between 60-70° C. for a period ranging between 3-5 h in followed by pouring the said solution on a glass plate and casting subsequently drying at temperature ranging between 11-14 hrs at 25-35° C. to obtain inter-polymer film;
• b) optionally, preparing an inter-polymer film by adding mixture of p-methylstyrene, divinylbenzene, benzoyl peroxide and toluene into melted mixture of binder under constant stirring at 80-95° C. for a period ranging between 3-5 hrs followed by increasing the temperature ranging between 130-140° C. to distill out the solvent from the polymer mixture to obtain noodles and cutting into small pellets subsequently keeping the said pellets in an oven at 75-80° C. for a period ranging between 12-16 hrs and after curing converting pellets into inter-polymer film;
• c) benzylic haloginating the inter-polymer film as obtained in step (a) or (b) by treating inter-polymer film with a halogenations agent in mole ratio 1:1 to 2.5:1 in respect ofp-methyl styrene, benzoyl peroxide and chlorinated solvent under stirring at temperature ranging between 75-80° C. for a period ranging 5-10 hrs under photo irradiation to obtain halogenated inter polymer film;
• d) providing quaternization of halogenated inter-polymer film as obtained in step (b) to obtain inter-polymer anion exchange membrane.
