Polythene.
The polymer "polythene".
Polyethene (polythene, polyethylene) is a chemical product.
Polythene - album - was created in 1996.
When polythene is rubbed with a cloth, electrons are transferred from the cloth to the polythene, causing the polythene to become negatively charged. This transfer of electrons creates an imbalance of charges between the two materials, resulting in the polythene having a negative charge.

plastics are of 5 types[1]- polythene[2]- polyvinyl chloride (PVC)[3]- orion/polyvinyl cyanide /polyacryl nitrile (PAN)[4]- polymethyl meth acrylate (PMMC)[5]- polysterene
When polythene is rubbed with wool, electrons are transferred from the wool to the polythene due to differences in their electronegativities. The polythene gains extra electrons, making it negatively charged, while the wool becomes positively charged due to losing electrons.
