Filed:

Sep 1, 1982

Appl. No.:

6/413907

Inventors:

Joseph S. Zannucci - Kingsport TN
Wayne P. Pruett - Kingsport TN

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

C09K 1520
C08K 516

US Classification:

252403

Abstract:

The invention relates to melamine group containing compounds which have been found to be effective ultraviolet stabilizers. The invention also relates to ultraviolet degradable organic compositions containing an amount of a melamine group containing compounds to prevent such degradation. These stabilizers are effective in the presence of other additives commonly employed in polymeric compositions including, for example, pigments, colorants, fillers, reinforcing agents and the like. These ultraviolet stabilizers may be incorporated into the organic compositions such as polymers by adding to the polymer melt or dissolved in the polymer dope, coated on the exterior of the shaped or molded article, film or extruded fiber.

International Classification:

C08K 534
C08K 535

US Classification:

260 458NT

Abstract:

This invention relates to oriented polyester shaped, molded, or formed objects having improved ultraviolet stability and to a process for producing the same and to compositions used in making such objects. More particularly, the invention relates to an oriented linear polyester film, fiber, foils, sheets, and other shaped, molded, or formed objects prepared from polyester compositions containing multichromophoric ultraviolet stabilizers which when oriented provide objects having improved weatherability. Multichromophoric ultraviolet stabilizers are those stabilizers which contain two or more moieties which, if isolated from one another, absorb a portion of the ultraviolet spectrum between 280 nm and 400 nm or an aromatic ester comprised of one or more of the above moieties and which on absorption of light the ester rearranges to a moiety which absorbs between 280 nm and 400 nm.

B32B 2736

US Classification:

428483

Abstract:

Disclosed are polyester substrates or sheets laminated with an acrylic film and having exceptionally improved resistance to surface deterioration on weathering. These laminates are especially suited for use in applications such as windows, signs, solar collectors, green house covers and the like which are subject to extended periods of outdoor exposure. Typical polyesters include modified poly(ethylene terephthalate), and modified poly(1,4-cyclohexylenedimethylene terephthalate) such as those of terephthalic acid with ethylene glycol and 1,4-cyclohexanedimethanol, e. g. , poly(69/31 molar-ethylene/1,4-cyclohexylenedimethylene terephthalate) and poly(65/35 molar-1,4-cyclohexylenedimethylene/ethylene terephthalate). The acrylic polymer films suitable forlamination to the polyester sheeting are homopolymers and copolymers prepared from either or both of the monomers H. sub. 2 C. dbd. CHCO. sub. 2 R and H. sub. 2 C. dbd. C(CH. sub. 3)CO. sub. 2 R. sup. 1 wherein R and R. sup.

Abstract:

Disclosed are novel copolyester materials having improved weatherability and useful, for example, as films, fibers, sheeting and the like in outdoor applications where long and daily exposure to actinic radiation is encountered. These copolyesters comprise, for example, polyethylene terephthalate containing a total of from about 0. 3 to about 5. 0%, preferably from about 0. 6 to about 2. 0% by weight of one or more moieties having the formula ##STR1## where R. sub. 1 is cyano, alkylcarbonyl, cycloalkylcarbonyl or arylcarbonyl; R. sub. 2 and R. sub. 3 are, for example, alkyl, cycloalkyl, or aryl which may be substituted with a large variety of groups; and --X-- is ortho, meta, or para to the -ylene linkage and is selected from groups of the formulae ##STR2## wherein R is alkylene of 1-10 carbons, aryl, or cycloalkyl, each of which may be substituted.
