2. Linear low-density polyethylene - Wikipedia

   en.wikipedia.org/.../Linear_low-density_polyethylene

   Linear low-density polyethylene (LLDPE) granules Linear low-density polyethylene ( LLDPE ) is a substantially linear polymer ( polyethylene ), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins .

   LLDPE is a substantially linear polymer with significant numbers of short branches, commonly made by copolymerization of ethylene with short-chain alpha-olefins (for example, 1-butene, 1-hexene, and 1-octene).

   For example, in the free-radical copolymerization of styrene maleic anhydride copolymer, r 1 = 0.097 and r 2 = 0.001, [11] so that most chains ending in styrene add a maleic anhydride unit, and almost all chains ending in maleic anhydride add a styrene unit. This leads to a predominantly alternating structure.

5. Ziegler–Natta catalyst - Wikipedia

   en.wikipedia.org/wiki/Ziegler–Natta_catalyst

   catalysts suitable for homopolymerization of ethylene and for ethylene/1-alkene copolymerization reactions leading to copolymers with a low 1-alkene content, 2–4 mol% (LLDPE resins), and; catalysts suitable for the synthesis of isotactic 1-alkenes.

6. Solution polymerization - Wikipedia

   en.wikipedia.org/wiki/Solution_polymerization

   Polyethylene (HDPE, LLDPE) - some grades are made by coordination polymerization in high boiling hydrocarbone solvents (above PE solution temperature). The advantage of this process is very high propagation rate allowing fast changes of product grades.

7. Low-density polyethylene - Wikipedia

   LDPE has SPI resin ID code 4 Schematic of LDPE branching structure. Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene.It was the first grade of polyethylene, produced in 1933 by John C. Swallow and M.W Perrin who were working for Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. [1]
