2 interactive concept widgets for Polymers. Drag any slider, change any number, and watch the formula and the answer update live. Built so you understand how each NEET problem actually works, not just the final number.

Polymer builder tool

Select any monomer to instantly see the polymer it forms: repeating unit formula, polymerisation type (addition / condensation / ring-opening), linkage formed, by-product, thermal behaviour, and NEET key fact. Covers Teflon, PVC, Nylon 6/6,6, Dacron, Bakelite, natural rubber, and more.

Polymer Builder Tool

Select a monomer to see the polymer it forms, its structure, polymerisation type, and NEET key facts.

Polyethylene (PE)
Addition Polymerisation
Thermoplastic
Monomer(s)

CH₂=CH₂

Repeating Unit

(-CH₂-CH₂-)n

Linkage formed

C-C single bond

By-product

None (no atoms lost)

NEET Note

LDPE = branched (low density, soft bags). HDPE = linear (high density, rigid pipes). Same monomer, different conditions give different products.

Real-world Uses
Plastic bags (LDPE)
Rigid pipes (HDPE)
Bottles
Packaging films
Polymerisation type:
Addition
Condensation
Ring-opening
Behaviour:
Thermoplastic
Thermosetting
Elastomer

Polymer classification engine

Click any polymer to see its full classification profile: source (natural/synthetic), mode (addition/condensation), structure (linear/branched/cross-linked), thermal behaviour (thermoplastic/thermosetting/elastomer), and biodegradability. Includes a quick-reference summary table of all 10 key NEET polymers.

Polymer Classification Engine

Click any polymer to see its complete classification profile across all five systems. Use this to build your NEET memory map.

Why it matters

Adding plasticisers to PVC makes it soft and flexible. Without them, it is hard and rigid. Same polymer, completely different feel.
