Versuchsvorschrift

Titration was effected by suspending the product (0.500g) in 95% ethanol (50 ml.) adding 0.5M sodium hydroxide (50 ml.), warming the mixture to reflux, cooling and back titrating with 0.5M hydrochloric acid using phenolphthalein as the indicator; it was found that 47.12 ml. of acid were required for neutralisation indicating 2.88 m.mole carboxyl/g of polymer.
