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. Dibasic acids reacts with dihydric alcohols … Pick out the wrong statement ?Read More...
