Background Information
definition of polymer
A large molecule made up of repeating monomers that are chemically bonded, that exist either naturally or synthetically
type of reactions
two main types
addition polymerization is when monomers contain double bonds, and no small molecules are released on formation
condensation polymerization is when monomers have two main function groups and they release a small molecule when bonded, like water
how can it be measured
density, melting point, flammability, solubility, infrared spectra
how can they be identified, classified and sorted
-
sorting method
based on reason for existence, thermal behavior, formation method
identification
Burn test for smell, flame colour, residue (whether they soften or char as well)
