Most poly(vinyl chloride) in common use contains, in addition to the polymers of vinyl chloride that constitute most of its mass, a substantially lower molecular weight substance such as a dioctyl phthalate. This added substance is called a "plasticizer", and even a fairly small amount of it can make an article of poly(vinyl chloride) much more flexible. However, there is much suspicion that plasticizers can have adverse health effects on humans when ingested, even in small quantitites, and it is known that plasticizers can be leached from the solid poly(vinly chloride) into water. Therefore, for use when there are health concerns about normally plasticized polymer (as in baby bottles) or greater rigidity is advantageous for a particular application, poly(vinly chloride) is also manufactured without any plasticizer; this is called "unplasticized".
how to makes this Polyvinyl?
Polyvinyl Chloride (or PVC) contains a double bond between the backbone carbon chain.
According to SpecialChem, an online network of industry experts, polyvinyl is a resin formed by combining different vinyl monomers. Polyvinyl chloride, polyvinyl acetate and polyvinyl alcohol are examples of polyvinyl resins. Polyvinyl acetate is often used to make glues and adhesives, or to coat paper and textiles to give them a shine. Polyvinyl acetate is also an ingredient in cosmetics.
Yes. PVC is polyvinyl chloride.

It stands for Unplasticized Polyvinyl Chloride
UPVC stands for Unplasticized Polyvinyl Chloride. It's a type of rigid and chemically resistant plastic used extensively in the construction of pipe installations and other infrastructural applications due to its durability, low cost, and resistance to water corrosion.
uPVC or un-plasticized polyvinyl chloride is manufactured the same way as all PVC resin is. The process takes ethylene and reacts it with chlorine to form ethylene dichloride (EDC). It is then reacted to form vinyl chloride monomer (VCM), which in turn is reacted to form Polyvinyl Chloride. (PVC).

The main difference between PVC (polyvinyl chloride) and uPVC (unplasticized polyvinyl chloride) pipes is the composition of the material. PVC pipes contain added plasticizers to make them more flexible, whereas uPVC pipes are rigid and do not contain plasticizers, making them better suited for pressure applications such as water supply lines. uPVC pipes are also more resistant to chemical corrosion and are typically used in plumbing and drainage systems.

how to makes this Polyvinyl?
As far as I know, uPVC (unplasticized polyvinyl chloride) sewer pipe is still a very costly specialty item, and currently only used for gutters and the like. PVC and uPVC are essentially the same thing expect for one difference. uPVC is not plasticized. The plasticizers in PVC are the main thing by which it causes enviromental damge. Mechanically speaking though, it would make no difference. PVC is very common and works quite well in all its applications. If you want to save major cash though, use ABS.
uPVC actually stands for unplasticised polyvinyl chloride. uPVC is also commonly known as rigid PVC and it is called this because it is hard and does not flex. This material doesn't not contain any phthalates or BPA, so it is actually quite safe. uPVC is so stable and safe that it is actually used to make dental retainers and mouthguards!
