Since polypropylene contain only carbon and hydrogen atoms, it does not poison environment after its disposal. However high melting point suggests that deterioration time in the land field will be long. ammendment: really? how exactly will it break down? and what time frame. to say it does not poison the environment after disposal is untrue.
To make plastics
Ha Ha Ha actually we can't differentiate between plastic and polymer because plastic itself is made of polymer.
Cellulose: Found in plant cell walls, it is the most abundant natural polymer. Chitin: Found in the exoskeletons of arthropods and the cell walls of fungi, it is a versatile natural polymer. Casein: A protein found in milk that can be used to create biodegradable plastics.
Plastic bags are typically manufactured from high density polypropylene (HDPE - plastic number 2) or low density polypropylene.
The simple answer is no! HDPE is a thermoplastic polymer and has a strong molecular structure, whereas the cellular plastics are foam-like air-filled cells and bubble structures. They are also lighter so HDPE is not cellular plastic. If you are wondering where to find HDPE plastics I highly suggest you check out these suppliers Ningeplastics, Acme Plastics, Professional Plastics, A&C Plastics, TAP Plastics, U.S. Plastic Corp.

Yes, plastic is typically made from polymers. Polymers are long chains of repeating molecules, and plastics are derived from these long chains. The properties of plastics can vary depending on the specific type of polymer used in their production.
Plastics are usually synthetic organic polymers. The first step to manufacturing plastics is to get the materials. Step 2 is to synthesize the polymer. Step 3 involves compounding the polymer into a material that can be used and step 4 involves shaping the plastic into it's form.

not usually, but would depend on the polymer
It's not that what they make plastics with.

The polymerization reaction produces rubber and plastics from organic molecules. In this reaction, monomers join together to form long chains of repeating units, creating the polymer structure of rubber and plastics.
