Similar to example 1, the monomer feed was prepared by mixing together vinyl acetate (86 g, 40%) and acrylic acid (65 g, 30%) monomers, and was fed into the reaction kettle over 2 hours. The initiator was fed over a total time of 152 mins.

Polyethylene terephthalate - Wikipedia

Another common modifier is isophthalic acid, replacing some of the 1,4-(para-) linked terephthalate units. The 1,2-(ortho-) or 1,3-(meta-) linkage produces an angle in the chain, which also disturbs crystallinity.Such copolymers are advantageous for certain molding applications, such as thermoforming, which is used for example to make tray or blister packaging from co-PET film, or amorphous .
