4、tion polymerizationpolymer categoriesthermoplastic only secondary bonds between molecules.-”plastic” or reshapable- melted and formed under pressure- higher tooling costspolymer categoriesthermoplastic only secondary bonds between molecules.-”plastic” or reshapable- melted and formed under pressure-

5、 higher tooling coststhermoset primary and secondary bonds between molecule segments.- cannot be reshaped- low viscosity in processing- cheaper toolingepoxy reaction:primary amineif an amine is on both ends you get a “crosslink”thermosetthermosetfrequent cross-links create 3-d networkamorphous polymer lightly crosslinkedsemicrystalline thermoplasticcrystallineexample: polyeth
