# 12 Condensation Polymerization: Preparation of Two Types of
Description In this lab students will synthesize two examples of condensation polymers a linear polyester and a cross-linked polyester Both esters are produced by the reaction of an acid anhydride (phthalic anhydride) and an alcohol Phthalic anhydride is the anhydride of phthalic acid 12-benzenedicarboxylic acid |

What is suspension polymerization?
may occur. On a commercial scale, Suspension Polymerization is carried out in jacketed, stainless steel or glass – lined stirred tanks, which may have a capacity of 20,000 gal or 75.5 m3. Suspension Polymerization produces small, uniform polymer spheres. These pellets. polymerization. This process overcomes the difficulty of heat control and
What is the difference between condensation and step-growth polymerization?
In condensation polymerization, the monomers are difunctional. As the monomers link together a small molecule, such as water, is released and must be removed to drive the reaction to completion. In a step-growth polymerization, the growing chains may react with each other to form even longer chains.
What is a condensate produced during esterification?
Esterification is a condensation reaction producing a small molecule called the condensate along with the ester. What condensate is produced during the synthesis of the linear and cross-linked polyesters? What happened to the condensate?
