    Abstract: N-(2,2,6,6-tetraalkyl-4-piperidinyl)amine-hydrazides of dicarboxylic acids contain a light stabilizing group, a heat stabilizing group, a 5-membered lactam ring and a reactive hydrazide functionality in the same molecule. The reactive stabilizers can be prepared by reacting 4-amino-2,2,6,6-tetraalkylpiperidines with dialkyl itaconates followed by hydrazinolysis of the ester group of the intermediate mono ester-amide. The compounds are useful for introducing permanent heat and light stability to coreactive polymers or copolymers. They are also useful in the stabilization of inert polymeric systems against the degradative effects of heat and light when merely mixed with, rather than reacted with, the polymers for which stabilization is sought.

    Abstract: Apparatus for modifying the surface region of a polymer article includes an applicator unit (20) defining a gap (26) extending therethrough. In use, the applicator unit is received within a treatment tank (180) filled with fluid, such as water, and immersed in the fluid and a polymer article is moved through the gap. A solvent is introduced into the gap through a channel (34) and subsequently substantially removed by a primary vacuum module (68). Wash water is then applied to the polymer article by a wash module (94) and the wash water is then removed by a secondary vacuum module (68) and/or a wiper (46) which contacts the surface of the polymer article. The solvent may modify the surface region of the article by dissolving surface imperfections or it may include a dissolved modifier ingredient which is then incorporated into the surface of the article.

    Abstract: On décrit un article translucide ou opaque en résine de chlorure de polyvinyle à surface modifiée et à stabilité UV, ainsi que son procédé de fabrication. L'article comprend un pigment coloré et est caractérisé en ce que ce dernier ne contient sensiblement pas de dioxyde de titane. La surface modifiée est sensiblement dépourvue de stabilisant et de solvant résiduels, et son aspect visuel ainsi que son degré de perfection superficielle sont sensiblement identiques à ceux de sa surface non modifiée. Ledit procédé est caractérisé en ce qu'il consiste à immerger l'article en chlorure de polyvinyle dans un milieu liquide approprié, à le mettre en contact avec une solution d'un stabilisant UV dans un solvant organique approprié, et à déplacer le stabilisant et le solvant résiduels dans un environnement non évaporatif, c'est-à-dire sans contact avec l'air.
