Title: Polymerisation Help
Post by: Most UniQue™ on April 27, 2011, 04:09:46 pm

Guys can any1 explain me in detail about polymerization (condensation and addition)? They are hard and I cant solve questions regarding them! Plz help me as soon as possible, i dont want to get bad cuz of this topic only!! Plz also solve a question as an example so that i can get how it is?

A significant proportion of clothing is made using polyster fibre. Polyster is also used to make plastic bottles for drinks. ployster is made by polymerising ethane-1,2-diol with benzene-1,4-dicarboxylic acid(terepthalic acid). As each ester link is made, a water molecule is lost - a condensation reation occurs. so the formation of a polyster is an example of condesation polymerisation.see in the figure(sry for not a clear image)
