A pressure-sensitive adhesive polymeric composition comprising: a butyl rubber; a polyurethane; an olefinic polymer component; and a filler that includes titanium dioxide, wherein said adhesive polymeric composition is pressure-sensitive, and where pressure-sensitive adhesive polymeric composition is a solids composition wherein said butyl rubber forms a matrix.

Adhesive compositions and tapes made therefrom that have improved bonding characteristics, particularly for bonding the tapes to a roofing structure, such as a roof membrane, are provided. The adhesive is chlorinated, and includes an elastomeric material. The adhesive is suitable for use on certain substrates without requiring a primer, such as thermoplastic polyolefin (TPO).

The present invention relates to an adhesive composition including: a butyl-based rubber; and a tackifier having a softening point of 90 C. or more.

The present invention relates to an adhesive composition including: a butyl-based rubber; and a tackifier having a softening point of 90 C. or more.

An adhesive composition is described comprising a tackifier and at least one grafted isobutylene copolymer. The grafted isobutylene copolymer has the formula: R.sup.1(R.sup.2Z) wherein R.sup.1 represents an isobutylene copolymer, R.sup.2 is a covalent bond or multivalent alkylene or arylene, and Z is a grafted polymer. Z is typically a homopolymer of copolymer comprising alkene repeat units, aralkylene repeat units, or a combination thereof. Also described are adhesive coated articles, methods of making adhesive coated articles, and grafted isobutylene polymers.
