1 MONOMER - POLİMER NEDİR?

2 Doğrusal Polimerler: Appearance of real linear polymer chains as recorded using an atomic force microscope on surface under liquid medium. Chain contour length for this polymer is ~204 nm; thickness is ~0.4 nm. (The contour length of a polymer chain is its length at maximum physically possible extension).
