摘要:
Coated articles having improved chemical resistance comprising an article formed from a moldable polymer coated on at least one surface with a coating composition comprising at least one vinyl ether oligomer compound, and at least one photoinitiator are disclosed. Coatings which also contain at least one acrylate compound and/or at least one epoxy compound are also disclosed. The articles are preferably made from polyesters. Methods for coating such articles are also disclosed.
摘要:
A method for reducing or eliminating plate-out during the process used to produce stretch blow molded containers from polyester preforms by crystallizing the low molecular weight polyester molecules in or on the preform exterior surface before stretch blow molding the preform into a container. The molecules are crystallized using a crystallization process selected from (1) treating the outer surface of the preform with a solvent that is capable of crystallizing low molecular weight polyester molecules in polyester or (2) heating the outer surface of the preform to a temperature and for a time suitable for crystallizing low molecular weight polyester molecules in polyester. Plate-out is reduced because the crystallized molecules do not migrate out of the preform and form plate-out deposits on the mold.
摘要:
Polyester containers having a reduced coefficient of friction (“COF”) are produced by increasing the surface roughness of the polyester using either thermal crystallization or solvent crystallization. Because the low COF reduces or eliminates friction between polyester containers, the containers do not become entangled and disrupt the manufacturing process. As a result, the containers move easily through typical conveying and filling lines in manufacturing processes that use the containers.

摘要:
Polyesters and polyester containers having a reduced coefficient of friction and improved clarity are produced using an antiblock agent comprising a dried talc having from about 20 to about 300 ppm water or a fatty acid tethered talc. The use of these talcs result in polyesters and polyester containers having a coefficient of less than about 1.0 and a clarity with haze values of less than about 4%.

The invetion is directed to a polymer-clay nanocomposite material comprising a melt-processible matrix oplymer and a layered clay material having decreased levels of extractable material, such as extractible salts of organic cations. This invention is also derected to processes for preparing polymer-clay nanocomposites, intercalates, exfoliates, and articles or products produced from nanocomposite materials.
摘要:
This invention relates to novel multilayer formed articles including, but not limited to containers such as bottles, tubes, pipes, preforms and films (including oriented films such as biaxially oriented) comprising a melt processible resin having dispersed therein a platelet filler. The multilayer formed articles have improved barrier while maintaining excellent clarity. More particularly, the multilayer structures of the present invention display haze values of less than about 2% and carrier resins which are substantially free from platelet particles having a diameter greater than about 15 microns.
