1.	What is the structure difference between HDP and LDP ? How does the structure account for different behaviour and nature , hence the use of a polymer ?
Answer» Solution :LDP has a branched structure and hence does not PACK well. As a result , it has LOW density. It is a transparent polymer of moderate tensile strength and HIGH toughness. It is flexible and is a poor conductor of electricity. It is widely used as a packaging material (in the form of thin PLASTIC films, bags etc.) , as insulation for electrical wires and cables , in the manufacturing of squeeze bottles , toys and flexible pipes. HDP , on the other hand , has linear structure and hence packs well. As a result, it has higher density and higher m.p. than LDP, It is a translucent polymer. It has greater toughness, hardness and tensile strength than LDP. It is used in the manufacture of containers (buckets , MUGS ,tubs etc.) housewares , pipes , bottles and toys.
