Dear Student,
The chemical formula is as follows -
1.PVC- polyvinyl chloride 
[-CH₂-CHCl-]_n
2.PET -Poly ethylene terepthalate
$[-OOC-C_6{H}_4-COO-C{H}_2-C{H}_2-{]}_n$
3.Teflon - polytetrafluoroethylene
$[-C{F}_2-C{F}_2-{]}_n$

​4. Polythene - polyethylene
$[-C{H}_2-C{H}_2-{]}_n$

5.Bakelite
$[-C_6{H}_{6}OC{H}_{2}O-{]}_n$

6.Melamine
$C_3{H}_6{N}_6$

7.Polyurethane
$[R-NHCOO-{]}_n$
8.Polyacrylonitrile
$[-C{H}_2-CH(CN)-{]}_n$
