US Patent:

6077889, Jun 20, 2000

Filed:

Mar 24, 1993

Appl. No.:

8/036607

Inventors:

Edmund Kwok-Leung Lau - Arlington TX
David K. Edge - Livonia MI

Assignee:

Solvay Engineered Polymers - Grand Prairie TX

International Classification:

C08K 534
B32B 904

US Classification:

524100

Abstract:

A light stabilizer package is disclosed. The light stabilizer package comprises a monomeric HALS having a pKa of no greater than 7, an ultraviolet light absorber and, optionally, a polymeric HALS having a pKa of less than 7. The light stabilizer package may be blended with a thermoplastic olefin to form a moldable light stable composition. An article comprising the moldable light stable composition may have an exterior surface that is at least partially coated.

Assignee:

Solvay Engineered Polymers - Grand Prairie TX

International Classification:

C08L 2312
C08L 2314
C08L 2316
C08K 318

US Classification:

524425

Abstract:

Thermoplastic olefinic, polymer blends which have superior physical properties and adherence for coating materials such as paints are disclosed. The blends may be formed from various combinations of thermoplastic components such as a crystalline isotactic propylene polymers and sequentially polymerized blends of polypropylene and ethylene-propylene copolymers, with elastomeric components such as copolymers of ethylene and butene, and copolymers of ethylene and octene which are produced with metallocene or Kaminsky catalysts. If desired, other components, such as fillers, can be included. The thermoplastic olefinic, polymer blends are suitable for automotive applications.

US Classification:

525240

Abstract:

Thermoplastic olefinic, polymer blends which have superior physical properties and adherence for coating materials such as paints are disclosed. The blends may be formed from various combinations of thermoplastic components such as homopolymers of propylene having an isotactic index which is greater than about 0. 93, and/or a crystallinity which is greater than about 56%, and sequentially polymerized blends of polypropylene and ethylene-propylene copolymers, with elastomeric components such as copolymers of ethylene and butene produced with metallocene or Kaminsky catalysts, and copolymers of ethylene and octene produced with metallocene or Kaminsky catalysts. If desired, other components, such as copolymers of ethylene with C. sub. 3 -C. sub. 15 alpha olefins or fillers, can be included.
