Question

Draw the structure of the polymer you would expect to obtain from
reaction of dimethyl terephthalate with a triol such as glycerol. Whatstructural feature would this new polymer have that was not present inDacron (Table 21-2)? How do you think this new feature might affectthe properties of the polymer?

Step-by-Step Solution

Answer

Thestructure of the polymer to get from dimethyl terephthalate reaction with triol such as glycerol can be drawn.

Step 1: Explaining the formation of the new structure

The formed polymer needs to have good tensile strength compared to Dacron which occurs to the increasing number of forming condensed rings.

Step 2: Drawing the structure

The structureof the polymer to get from dimethyl terephthalate reaction with triol such as glycerol can be drawn as,
