(b) Addition polymers are obtained by the polymerisation of olefins and without the loss of small molecules such as H2O and NH3
(c) Condensation polymers are obtained with the loss of small molecules such as H2O and NH3
(d) Homopolymers contain monomer units of only one kind. Since, bakelite is a polymer of formaldehyde (HCHO) and phenol (C6H5OH) and formed with the loss of water molecules, it is a synthetic condensation copolymer.
