Vedclass · Answer

(B) The given structure is $PHBV$,which stands for poly-$\beta$-hydroxybutyrate-co-$\beta$-hydroxyvalerate. It is a copolymer formed by the condensation polymerization of $3$-hydroxybutanoic acid and $3$-hydroxypentanoic acid. It is a biodegradable,thermoplastic polyester. Therefore,statements $I$ (condensation and biodegradable),$II$ (biodegradable and thermoplastic),and $IV$ (polyester and thermoplastic) are correct. Thus,the correct combination is $I$,$II$ and $IV$.

The structure given below is an example of
$I$. $A$ condensation and biodegradable polymer.
$II$. $A$ biodegradable and thermoplastic polymer.
$III$. $A$ biodegradable and thermosetting polymer.
$IV$. $A$ polyester and thermoplastic polymer.
