Question
a.
Linear polymers are formed from bifunctional groups only and are normally thermoplastic.
b.
Cross-linked branched chain polymers are either elastometric or thermosetting.
c.
Branching in case of cross-linked polymers caused by small amount of impurities in bifunctional monomer formulation reduces its solubility and increases the softening point.
d.
