Patent number: 5223339Abstract: Excellent stabilization to bright sunlight, is obtained in polypropylene (PP) fibers pigmented with Red 144, by combining the pigment with N-(substituted)-1-(piperazin-2-one alkyl)-.alpha.-(3,5-dialkyl-4-hydroxyphenyl)-.alpha.,.alpha.-substituted acetamide ("3,5-DHPZNA" for brevity). Stabilization of the red color is obtained for as long as the PP fibers themselves are stabilized by the 3,5-DHPZNA. 3,5-DHPZNA is a known hybrid stabilizer having a hindered amine N-(substituted)-1-(piperazin-2-one alkyl) group at one end, and a hinderd phenol (3,5-dialkyl-4-hydroxyphenyl) group at the other. This particular hybrid, containing a piperazinone group, combined through a disubstituted alpha carbon atom of the acetamide in a single molecule, affords the advantages of each group with respect to its stabilization of the fiber against degradation, but without the expected adverse interaction of each group with Red 144 pigment. With 3,5-DHPZNA and Red 144 pigment, essentially no secondary stabilizer is necessary.Type: GrantFiled: September 9, 1991Date of Patent: June 29, 1993Assignee: The B. F.

Patent number: 5216053Abstract: Chlorinated polyethylene mastic adhesive compositions, and process for the production of such compositions, formed from chlorinated polyethylene and a compatible plasticizer. These mastic compositions are useful for bonding and sealing together membranes, particularly chlorinated polyethylene membranes, at ambient conditions without application of heat. The ability to form seals of high peel strength in roofing applications without the use of heat is of particular importance. In another embodiment however, cross linking agents can be incorporated within the recipe, and seals of even greater peel strength obtained. Heat is required in the sealing operation in this instance to produce cross linking of the polymer. One thus has the choice of forming adhesives of high peel strength for roofing applications without any necessity of using heat; or, alternatively, to form adhesives of even greater peel strength with the use of heat.Type: GrantFiled: November 27, 1990Date of Patent: June 1, 1993Assignee: The Dow Chemical CompanyInventors: Edward Jones, Norman E.
