The polymer X-consists of linear molecules and is closely packed. It is prepared in the presence of trimethylammoniumpropyl and titanium tetrachloride under low pressure. The polymer X is

Options

  1. AHigh density polythene
  2. BPolyacrylonitrile
  3. CLow density polythene
  4. DPolytetrafluoroethane

Correct answer

A. High density polythene

Step-by-step solution

High-density polyethylene (HDPE) is commonly prepared in the presence of a Ziegler-Natta catalyst. The information provided describes the preparation and characteristics of a high-density polyethylene (HDPE) polymer. HDPE is a widely used thermoplastic polymer known for its high strength, durability, and excellent chemical resistance. The presence of trimethylammoniumpropyl (TMP) and titanium tetrachloride ( TiCl 4 ) indicates that the polymerization process is likely carried out using a Ziegler-Natta catalyst syst
