The properties of anything made out of polymers really reflect what's going on at the ultra-tiny (molecular) level. So, things that are made of polymers look, feel, and act depending on how their atoms and molecules are connected, as well as which ones we use to begin with!Some are rubbery, like a bouncy ball, some are sticky and gooey, and some are hard and tough, like a skateboard.he properties of anything made out of polymers really reflect what's going on at the ultra-tiny (molecular) level.
