Answer 2

Answer:

1. USES OF PVC:

for making Raincoat,  Garden hoses , Seat cover

2. Plastic is made by process known as Polymerization

Explanation:

1. PVC stands Poly Vinyl Chloride. It is thermoplastic

thermoplastic is a plastic which can become soft on heating. That means it can be recycled many number of times.

2. Monomer : a monomer is a single molecule that molecule can bond with other identical monomer to form a polymer.

example of monomers: polyester is a polymer which has a monomer ester,

polymer is a "GREEK" word in which poly meaning many and "ester" meaning units. it is a large molecule made of many small monomer

polymerization: it is a process of converting a monomer into  a single large polymer.

"IN INDUSTRY USEING ' POLYMERIZATION REACTOR" MONOMERS ARE CONVERTED INTO POLYMERS

ADDITIONAL INFOS:

Plastic is of 2 types thermoplastic, thermosetting plastic

Thermoplastic:  is a plastic which can become soft on heating. That means it can be recycled many number of times.

example: PVC, PET, POLYTHENE

PET stands of poly ethylene theraphthalate

Thermosetting plastic:  it can be moulded one time cant be deformed.

that means recycling can`t be done. but these plastic has various uses

example: bakelite, melamine
