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
- AHigh density polythene
- BPolyacrylonitrile
- CLow density polythene
- 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 () indicates that the polymerization process is likely carried out using a Ziegler-Natta catalyst system. This catalyst system enables the production of high-density polyethylene by controlling the polymerization conditions.
