Polyester is a category of polymers, but in common parlance, the word typically refers to polyethylene terephthalate. Fabrics are often woven from threads made from this polymer, which can by dyed into virtually any colour. The colour of un-dyed polyester depends on whether the polymer is formed from naturally occurring chemicals or synthetic chemicals (amongs many other factors). The un-dyed colour will likely be white or grey.

The chemical name for Polypropylene is poly(propene).
What is the difference between isotactic polypropylene and syndiotactic polypropylene?
The difference between isotactic polypropylene and syndiotactic polypropylene lies in the arrangement of the propylene monomer units in the polymer chain. In isotactic polypropylene, all the methyl groups of the propylene units are on the same side of the polymer chain, while in syndiotactic polypropylene, the methyl groups alternate sides. This difference in arrangement affects the properties and crystallinity of the polymer.
