Procedure for production of a chemical-resistant halogenous plastic. Reactive groups are added to a halogenous polymer and the polymer is cross-linked by reaction with a multifunctional organic compound under the influence of heat during or after the processing of the material. PVC is a favoured polymer, but the method is also applicable to the production of cross-linked products from other haloge...

Amorphous and semi-crystalline films comprised of a lactide polymer. The lactide polymer comprises poly(lactide) polymer chains, residual lactide in concentration of less than about 5 percent by weight and water in a concentration not greater than about 2000 parts-per-million. Processes for manufacturing amorphous and semi-crystalline films with the lactide polymer composition are also disclosed.

A barrier coating is formed on a polymeric article, such as on the interior of a thermoplastic container. An oxidizing gas is converted to a plasma in a plasma chamber remote from the treatment chamber. The resulting plasma-activated oxidizing species are delivered to the interior of the container. An organosilicon reactant vapor is separately but simultaneously delivered to the interior of the co...
