# 12 Condensation Polymerization ... - Terrific Science

Developed through the National Science Foundation-fundedPartnership for the Advancement of Chemical Technology (PACT)1# 12 Condensation Polymerization : Preparation of TwoTypes of PolyestersSubmitted by: Arturo Contreras, Visiting Scholar, Center for ChemicalEducation, Miami University, Middletown, OH; 1996 this lab, students will synthesize two examples of Condensation polymers, a linearpolyester and a cross-linked polyester. Both esters are produced by the reaction of an acidanhydride (phthalic anhydride) and an alcohol. Phthalic anhydride is the anhydride ofphthalic acid, 1,2-benzenedicarboxylic acid. In the case of the linear polyester, the alcohol isa diol (ethylene glycol).

hardness, scratch resistance, and solubility in different solvents (water, alcohol, acetone, etc.) 10. Turn in samples of your products along with the properties determined above and the answers to the questions. Questions. 1. Esterification is a condensation reaction producing a small molecule called the condensate along with the ester.

A standard makes initial data cleaning easier because you don’t need to start from scratch and reinvent the wheel every time. The tidy data standard has been designed to facilitate initial exploration and analysis of the data, and to simplify the development of data analysis tools that work well together. Current tools often require translation.
