This polymer has attractive processing properties. 5 kilograms at 5 dpf is 20,000 miles • Few commercial fibers are produced at a scale of less than 500 tons – The length at 5 dpf is ~ . ppt, 240 KB. Can be produced with close dimensional tolerances. The monomers that make up polymers are linked through polymerization reactions. " Similar presentations Polymer Chemistry CHEM List of Topics No. e.
