unplasticized poly vinyl chloride
FPO stands for Flexible Polyolefin. An olefin is a chemical compound with at least one carbon atom to carbon atom double bond. An example is the simple olefin ethylene (C2H4). These molecules join together to form a polyolefin, for example poly-ethylene, hence a polyolefin. You can have thermoplastic polyolefins (TPOs) or polyolefin elastomers, eg (EPDM rubber).
Ferric Chloride is an intensely hygroscopic chemicaland thus will literally suck water from the air, dissolving into this water spontaneously forming a dark brown solution. Keeping it in an airtight container prevents this, keeping the crystals in solid form.
In the context of electrical cables, PVC and XLPE are two materials used as insulation. XLPE has got more capacity to hold on incase of high temperature. XLPE will not deteriorate it's insulating property until it reaches 90 degree celsius. It will not suddenly lose it's insulating property if the themperature jumps just above 90. But the overall life of the cable will be reduced. PVC can withstand temperatures only upto 70 degree Celsius. PVC is cheaper than XPLE, hence it's find it's place in market today. PVC is a thermo plastic where as XLPE is thermosetting plastic. PVC - Poly Vinyl chloride XLPE - Cross linked Poly Ethylene
The answer is somewhat complex sounding, but basically describes the chemical composition of the, "PVC" Pipe you are probably wondering about. Materials are cool!

It is a vinyl polymer consisting of vinyl groups (ethenyls) that are bound to chlorine.Polyvinyl chloride is the third most widely produced plastic, after polyethylene and polypropylene.[3] Over 50% of PVC manufactured is used in construction,[citation needed] because it is cheap, durable, and easy to assemble. PVC production is expected to exceed 40 million tons by 2016.[4]It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is used in clothing and upholstery, and to make flexible hoses and tubing, flooring, to roofing membranes, and electrical cable insulation. It is also commonly used in figurines and in inflatable products such as waterbeds, pool toys, and inflatable structures.citation: wikipedia.com
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).

Unplasticized poly vinyl chloride
unplasticized poly vinyl chloride
In case of vinyl chloride Chlorine undergoes the conjugation of vinyl grope having having resonating structure vinyl chloride acquire Double Bond character hence it is difficult to form easily. H2C=CH is less stable. In case of ethyl chloride there is only single bond then it is easier to break then vinyl chloride is less reactive then ethyl chloride. CH3=CH2 IS more stable.
Yes, the heat of reaction is negative therefore indicating an exothermic reaction
Vinyl chloride is a chemical intermediate, not a final product. Due to the hazardous nature of vinyl chloride to human health there are no end products that use vinyl chloride in its monomer form. Polyvinyl chloride is very stable, storable, and nowhere near as acutely hazardous as the monomer. Vinyl chloride liquid is fed to polymerization reactors where it is converted from a monomer to a polymer PVC. The final product of the polymerization process is PVC in either a flake or pellet form. From its flake or pellet form PVC is sold to companies that heat and mold the PVC into end products such as PVC pipe and bottles. Tens of billions of pounds of PVC are sold on the global market each year. Until 1974, vinyl chloride was used in aerosol spray propellant. Prior to the removal of vinyl chloride from hair spray the accumulation of vinyl chloride vapor in hair salons may have exceeded the NOAEL (No Observable Adverse Effect Level) exposure guidelines. Vinyl chloride was briefly used as an inhalational anaesthetic, in a similar vein to ethyl chloride, though its toxicity forced this practice to be abandoned.
A strongly exothermic reaction to produce a salt, sodium chloride.
It will form sodium chloride and sulfur hydroxide
The plastic Poly Vinyl Chloride is commonly abbreviated to PVC. UPVC is Unplasticised Poly Vinyl Chloride and is a rigid form of PVC often used in the building industry as a low-maintenance material.
This reaction produce lead chloride which is a white precipitate, though if the chloride concentration is considerably high, it'll not form.
acetic anhydride and sodium chloride will form.
