PET and Mylar + PE bottles
We're doing organic chemistry in my chem 2 class right now and today we
watched a video on polymers. It fetured the invintor of the plastic pop
bottle. He sai that the meterial used was basicly two layers of
polyethaline with the molecular chains perpandicular to each other. He
referered to it by its systematic name, which I don't remember, and then
abrieviated it "PET". I rembered from some of the messages in the list
archive that this is the same as Mylar. So I looked up Mylar in a big
reference book during my lunch break and I found that PET and Mylar are
the same, but the PE stands for polyester not polyethaline. So what I'm
thinking is that these are two different polymers that have the same
abrieviation, can anyone confirm/ disprove that?
I noticed that some dishwashing detergant bottles appear to be made out
of ldpe/hdpe. They have the milky white colour and are flexible.
They also appear to be unpigmented. Clear squeze bottles could also be
used. I'm sure there must be some where to get these cheaply.
Any responses would be greatly appriciated
