Detailed Solution

Bakelite is
(i) Condensation polymer of phenol and formaldehyde
(ii) Cross-linked polymer
Cross-linked polymers are insoluble in all solvents because polymer chains are tied together by strong covalent bonds.
(1) Addition polymer:
Polymer formed by simple linking of monomers. During formation of addition polymer other products are not formed. Monomers generally contain C–C double bonds

Examples: Polystyerene, Polyethylene
.
(2) Brached chain polymer:
These polymers contains main chain with smaller chain as branch of main chain. In other words, secondary polymer chain linked to a primary backbone. Example: Polypropylene.
