Abstract

A pressure-sensitive adhesive polymeric composition comprising the blend or reaction product of butyl rubber, an olefinic polymer component, filler that includes titanium dioxide, and an unfunctionalized phenolic resin, where the composition is devoid of isocyanate or isocyanate residue.

First claim

What is claimed is:

1. A pressure-sensitive adhesive polymeric composition comprising the blend or reaction product of:
i. butyl rubber;
ii. an olefinic polymer component;
iii. filler that includes titanium dioxide; and
iv. an unfunctionalized phenolic resin, where the composition is devoid of isocyanate or isocyanate residue.

2. The composition of claim 1 , where said composition further comprises an oil.

3. The composition of claim 1 , where the butyl rubber is a halogenated butyl rubber.

4. The composition of claim 1 , where said filler includes at least 25 weight percent titanium dioxide.

5. The composition of claim 1 , where said filler includes at least 50 weight percent titanium dioxide.

6. The composition of claim 1 , where said filler includes at least 75 weight percent titanium dioxide.

7. The composition of claim 1 , where said composition is formed in the presence of an amine catalyst.

8. The composition of claim 7 , where said amine catalyst is triethylenediamine (TEDA), dimethylcyclohexylamine (DMCHA), dimethylethanolamine (DMEA), tetramethylbutanediamine (TMBDA), pentamethyldipropylenetriamine, N-(3-dimethylaminopropyl)-N,N-diisopropanolamine, 1,3,5-(tris(3-dimethylamino)propyl)-hexahydro-s-triazine, bis-(2-dimethylaminoethyl)ether, N-ethylmorpholine, triethylamine (TEA), 1,8-diazabicyclo[5.4.0]undecene-7 (DBU), pentamethyldiethylenetriamine (PMDETA), benzyldimethylamine (BDMA), pentamethyldiethylene triamine (PMDETA), 2,4,6-tris[(dimethylamino)methyl]phenol, tributyl amine, N-methyl morpholine, or N-ethyl morpholine.

9. The composition of claim 1 , where said olefinic polymer component includes a copolymer of propylene and an olefin.

10. The composition of claim 9 , where said olefin is ethylene.

11. The composition of claim 9 , where said copolymer includes at least 60 weight percent of said propylene.

12. The composition of claim 9 , where said copolymer includes at least 80 weight percent of said propylene.

13. The composition of claim 9 , where said copolymer includes at least 85 weight percent of said propylene.

14. The composition of claim 9 , where said copolymer includes at least 90 weight percent of said propylene.

15. The composition of claim 1 , where said composition includes at least 35 weight percent of said butyl rubber.

16. The composition of claim 1 , where said composition includes at least 40 weight percent of said butyl rubber.

17. The composition of claim 1 , where said composition includes at least 45 weight percent of said butyl rubber.

18. The composition of claim 1 , where said composition includes less than 4 weight percent of said unfunctionalized phenolic resin.

19. The composition of claim 1 , where said composition includes less than 2 weight percent of said unfunctionalized phenolic resin.

20. The composition of claim 1 , where said composition includes less than 0.5 weight percent of said unfunctionalized phenolic resin.

21. The composition of claim 1 , where said composition includes at least 0.1 weight percent of said filler.

22. The composition of claim 1 , where said composition includes at least 0.5 weight percent of said filler.

23. The composition of claim 1 , where said composition includes at least 1 weight percent of said filler.

24. The composition of claim 1 , where said composition has a whiteness of at least an L value of 70.

25. The composition of claim 1 , where said composition has a whiteness of at least an L value of 75.

26. The composition of claim 1 , where said composition has a whiteness of at least an L value of 80.
