| paraxylene |
| One of the forms of xylene, paraxylene is used to make polyesters, which have applications in clothing, packaging and plastic bottles. The most widely-used polyester is polyethylene terephthalate (PET), used in lightweight, recyclable soft drinks bottles, as fibres in clothing, as a filling for anoraks and duvets, in car tyre cords and conveyor belts. It can also be made into a film that is used in video and audiotapes and x-ray films. |

| partition coefficient (n-octanol/water) |
| Distribution coefficient used to evaluate the harm the substance can cause to environment. Higher values indicate higher chance of accumulation of the substance in biological material. |
|
| patent |
| A patent is a passive – protective right limited in time and geographically. The granting of a patent to an inventor does not, in itself, allow the inventor to practice the invention. Rather, it enables the patentee to prohibit others from commercially exploiting the invention for a certain period of time and in a defined geographical area. A patent is a deal, whereby an inventor agrees to disclose the invention and how to use it to the public, promoting further technological advance. In return, if the invention is new, involves an inventive step and is industrially applicable, the inventor receives a patent. This gives the inventor the possibility of profiting from the investments made for the invention. |
