US Patent:

47512695, Jun 14, 1988

Filed:

Apr 3, 1987

Appl. No.:

7/034409

Inventors:

Thomas J. Bonk - Stillwater MN
Tsung-I Chen - Woodbury MN
Patricia M. Olson - Minneapolis MN
Douglas E. Weiss - Minneapolis MN

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

C08L 6128

US Classification:

525163

Abstract:

A crosslinked pressure-sensitive high shear adhesive is provided which is comprised of: (a) an acrylate terpolymer comprised of (i) at least one alkyl acrylate wherein the alkyl group has at least 5 carbon atoms and wherein a major portion of the alkyls have an alkyl group having from 5 to 12 carbon atoms; (ii) a second alkyl acrylate wherein the alkyl group has from 1 to 4 carbon atoms; (iii) at least one copolymerizable monoethylenically monomer selected from the group consisting of acrylic acid, methacrylic acid and itaconic acid; and (b) an amine formaldehyde condensate, in an amount of from about 0. 8 to 10 percent by weight of the terpolymer. The pressure sensitive adhesive is particularly useful when it is combined with a reinforcing web and a reinforcing filler and applied to a carrier to form an adhesive tape. The adhesive is particularly useful in adhering the edges of a heat-recoverable sheet to one another to secure the closure during the closure process. A chromophore-substituted trihalomethyltriazine is preferably used as an additional crosslinking agent.

C12N 1512
C07K 14705

US Classification:

435 72

Abstract:

A new endothelin B receptor has been identified, and the amino acid and nucleotide sequence of the receptor are provided. The nucleotide sequence is useful to construct expression cassettes and vectors to produce host cells which are capable of expressing the receptor, its mutants, fragments, or fusions. Such polypeptides are useful for identifying new endothelin agonists and antagonists.

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

B32B 700

US Classification:

428 57

Abstract:

A heat-recoverable closure with a crosslinked pressure-sensitive adhesive is provided. The closure member is comprised of a heat-recoverable sheet and a layer of crosslinked pressure-sensitive adhesive, which maintains the closure of the closure member having the recovery process. The combination of a high surface energy heat-recoverable sheet and the crosslinked pressure-sensitive adhesive yield an article having excellent performance as a closure member.
