For much of this time, the primary source of the plastic monomer chains, such as ethylene W and propylene W, has always been from the processing of crude oil and petroleum. This also has the effects of producing other organic compounds such as benzene W and xylene W which can then be used to produce offshoots from the initial monomer chains ...
