Reference: AQA
Strong covalent bonds within a layer need much energy to break, while weak forces between layers let them slide, so graphite has a very high melting point but is soft and slippery.
The value of n affects the size and properties of the polymer, such as its strength and melting point, because longer chains have stronger intermolecular forces between them.
The bonding explains the very high melting points, hardness or softness, and electrical behaviour of these substances.
