Vedclass · Answer

(B) Low density polythene $(LDPE)$ is a poor conductor of electricity. Its synthesis involves the polymerization of ethene at high pressure $(1000-2000 \ atm)$ and temperatures $(350-570 \ K)$ in the presence of traces of dioxygen or a peroxide initiator as a catalyst. $LDPE$ is chemically inert and tough but flexible,making it suitable for squeeze bottles,toys,and flexible pipes. High density polythene $(HDPE)$ is used in the manufacture of buckets,dust-bins,and bottles. Therefore,the statement that $LDPE$ is used in the manufacture of buckets and dust-bins is $FALSE$.
