The present PE and polypropylene prices still do not allow for acceptable margins under the current market conditions. Based on this situation, Dow Plastics announced a price increase in Europe of 100 per metric tonne above January 2003 pricing levels for all polypropylene resins.

Continuous stirred-tank reactors (CSTRs) are used for large productions of a reduced number of polymer grades. Coordination catalysts are used in the production of LLDPE by solution polymerization (Dowlex, DSM Compact process [29]), of HDPE in slurry (Mitsui CX-process [30]) and of polypropylene in stirred bed gas phase reactors (BP process [22], Novolen process [31]). LDPE and ethylene-vinyl acetate copolymers (EVA) are produced by free-radical polymerization in bulk in a continuous autoclave reactor [30]. A substantial fraction of the SBR used for tires is produced by coagulating the SBR latex produced by emulsion polymerization in a battery of about 10 CSTRs in series [32]. The CSTRs are characterized by a broad residence time distribution, which affects to product properties. For example, latexes with narrow particle size distribution cannot be produced in CSTRs. 

In 1992 the 3 M disclosed blends that comprised 100 parts VLDPE [Flexomer or Attane 80-95 mol% ethylene and 5 mol% C4 g comonomer(s)] and 15-600 parts m-LLDPE [DOWLEX ethylene copolymer with 2-8 mol% Cg]. The blends showed excellent processability. Formed into 10-300 pm thick films, they were used for transdermal drug delivery devices as single-layer backings. The films were clear, colorless, transparent to visible light, and sealable at relatively low temperature. They were permeable to O2, stable to various common components of transdermal delivery devices, strong, and comfortable and did not absorb significant amounts of common elements of transdermal carriers (Godbey and Martin 1993, 1994).

Linear low density polyethylene (LLDPE) of mark Dowlex-2032, having melt flow index 2.0 g/10 min and density 926 kg/m that corresponds to crystallinity degree of 0.49, used as a matrix polymer. Modified Na -montmorillonite (MMT), obtained by cation exchange reaction between MMT and quatemaiy ammonium ions, was used as nano filler MMT contents makes up 1-7 mass% [4]. 

The Dow Chemical Company developed the solution polymerization process with the Dowlex tradename in the 1970s to manufacture ethylene/1-octene linear low-density polyethylene (LLDPE) copolymers. The process is proprietary and not available for license. The ethylene/1-octene copolymers exhibit many superior physical properties relative to other ethylene copolymers based on 1-butene or 1-hexene.
