Question

Draw the diagram showing the presence of linear polymers in a thermoplastic and cross.​

Answer 1

━━━━━━━━━━━━━━━━━━━━

Answer:-

• Plastics are polymers of simple molecules (monomers).

• The arrangement of simple molecules,in different polymers,isn't of the same type.

Thermoplastics:-

• There are certain plastics where monomers are arranged In a straight chain.

• Such plastics are said to have Linear Arrangement of molecules; they are generally know as Thermoplastics.

• These plastics can be deformed easily on heating and can be remoulded into a new shape.

Example -

Polythene, Polyvinyl Chloride,Nylon,Polysterene and Terylene etc.

Thetmosetting plastics:-

• In some other plastics,the momomers are cross-linked. Such plastics are said to have cross-linked arrangements; they're generally known as Thermosetting Plastics.

• These plastics cannot be deformed on heating and therefore,cannot be remoulded again.

Example -

Bakelite and Melamine
