TUBULAR REACTOR POLYMERIZATION INITIATOR INJECTOR DEVICE, TUBULAR REACTOR FOR CONTINUOUS POLYMERIZATION OF OLEFINS, AND A PROCESS FOR PRODUCTION OF POLYMERS AND COPOLYMERS OF ETHYLENE
The present invention refers, in its generality, to a tubular reactor for homo or copolymerization of olefins, with one of more initiator injection devices. The invention also refers to an initiator device in a process fluid stream in a reactor polymerization reactor, and to a process for the production of polymers and copolymers of ethylene, particularly low density polymers (LDPE), that use the said device.
Solution process for fabricating high-performance organic thin-film transistors
The present invention relates to a solution or ink composition for fabricating high-performance thin-film transistors. The solution or ink comprises an organic semiconductor and a mediating polymer such as polyacrylonitrile, polystyrene, or the like or mixture thereof, in an organic solvent such as chlorobenzene or dichlorobenzene. The percentage ratio by weight of semiconductor:mediating polymer ranges from 5:95 to 95:5, and preferably from 20:80 to 80:20. The solution or ink is used to fabricate via solution coating or printing a semiconductor film, followed by drying and thermal annealing if necessary to provide a channel semiconductor for organic thin-film transistors (OTFTs). The resulting OTFT device with said channel semiconductor has afforded OTFT performance, particularly field-effect mobility and current on/off ratio that are superior to those OTFTs with channel semiconductors fabricated without a mediating polymer.

CORROSION RESISTANT COMPOSITIONS AND METHODS
Coatings for a substrate include a paint or a lacquer and about 0.1% or more particles of a bi-axially oriented metalized polymer film. The film may not be soluble in a solvent or a dispersion medium of the paint or the lacquer. Coatings may be formed by bi-axially orienting a polymer film to obtain a bi-axially oriented polymeric film having thickness of at least 1 followed by a vacuum metalizing to obtain a bi-axially oriented metalized polymer film, shredding the bi-axially oriented metalized polymer film to form the particles to at least 11 mm, selecting a solvent as system or a dispersion medium of paint in which the particles of the polymer film is not substantially soluble, preparing a paint or a coating composition by using selected solvent, and dispersing the shredded particles of oriented metalized polymer film in the paint as a primer, under coat, or top coat.

Process for Producing Thin Coatings on Film
Conventional atomic layer deposition technology is modified to increase its cost-effective viability for use in producing thinly coated flexible packaging film. In one embodiment a thinly coated flexible substrate, e.g., a polyolefin film, is made by a process comprising the steps of: (A) Dissolving a self-limiting precursor in a solvent to form a solution of dissolved self-limiting precursor in the solvent, (B) Applying the solution to a facial surface of a flexible polymer film so that at least a portion of the dissolved self-limiting precursor attaches to the facial surface of the film and the solution is at least partially depleted of self-limiting precursor, and (C) Curing the attached self-limiting precursor by contact with oxygen
