When monomers a and b are copolymerized, an azeotrope (polymer composition same as feed) is formed at a ratio of 7 mol of a to 3 mol of b. if monomer b is known not to homopolymerize, (a) what polymer composition (mole fraction of a) will result initially when a mixture of 9 mol of a and 1 mol of b is polymerized? (b) will polymer formed after 50% conversion from an initial mixture of 4 mol of a and 6 mol of b contain more a than polymer formed at 1% conversion? less a than polymer formed at 1% conversion? 3 1 2 same fraction of a as polymer formed at 1% conversion?
