There are a series of alcohols. Methanol has one carbon atom, ethanol two
(ethyl or drinkable alcohol). There are three, and four carbon alcohols
which are liquid. Then as more carbon atoms are involved the alcohols
become solid and/or waxy. Butanol and propanol are examples of +2 carbon
alcohols.

Both the same. Nothing, as far as I know, sticks to polyethylene. Thus you
cannot glue it, only weld it. Not too inferior really. It makes good water
pipe. Very impermeable! uPVC is worth thinking about. Impermeable to
water too. But does not like some petrochemicals. Can be glued readily.
