US Patent:

6894116, May 17, 2005

Filed:

Aug 15, 2002

Appl. No.:

10/219403

Inventors:

John Ta-Yuan Lai - Broadview Heights OH, US
Carole Angele Lepilleur - Akron OH, US
Carl Duane Weber - Copley OH, US
David Richard Egan - Stow OH, US
Deborah Susan Filla - Twinsburg OH, US

Assignee:

Noveon IP Holdings Corp. - Cleveland OH

International Classification:

C08F008/00
C08F283/00
C08L063/00
C08G059/14
C07C329/00

US Classification:

525107, 525525, 525535, 528419, 549561, 549562, 558243

Abstract:

A toughener comprising a trithiocarbonate polymer having an epoxy end group is described which is utilized with various thermosettable polymers such as epoxy, polyurethane, and the like. A toughened composition is made by curing the thermosettable polymer and the toughener utilizing various curing agents.

US Patent:

Filed:

Feb 19, 2004

Appl. No.:

10/782363

Inventors:

Carole Lepilleur - Akron OH, US
David Egan - Stow OH, US
Carl Weber - Copley OH, US

International Classification:

C08K005/41

US Classification:

525524000

Abstract:

A vinyl ester resin is derived from the reaction of an unsaturated acid with an epoxy terminated polymer made from a dithio or a trithio initiator, and optionally from an epoxy resin. The vinyl ester resin can be blended with a miscible toughener and a diluent to provide a time stable system and subsequently crosslink to provide a composition with improved toughening properties.

Filed:

Oct 15, 2007

Appl. No.:

11/974606

Inventors:

Carl Duane Weber - Copley OH, US
David Richard Egan - Stow OH, US

International Classification:

C08L 77/00

US Classification:

525181

Abstract:

An uncured liquid epoxy composition comprises a liquid epoxy resin and a) a tri-amine terminated polyether toughener optionally adducted with an epoxy resin, or a mixture of said tri-amine terminated polyether toughener optionally have an epoxy adduct thereon with a core-shell copolymer or with an epoxidized carboxyl terminated butadiene-acrylonitrile copolymer; or b) an amine terminated tri-block polyether toughener optionally adducted with an epoxy resin, or a mixture of said amine terminated tri-block polyether toughener optionally having an epoxy adducted thereon with a core-shell copolymer or with an epoxidized carboxyl terminated butadiene-acrylonitrile copolymer. The uncured toughener composition need not contain any high molecular weight polymers or material and is utilized as a low viscosity paste adhesive having good storage stability, and when cured has very good low temperature peel strength at minus 40 C. along with very good ambient temperature toughness which correlates with improved higher speed impact resistance. The epoxy compositions are suitable for use as an adhesive in the aerospace or automotive fields wherein good low temperature performance properties and improved resistance to impact are desired.

US Classification:

524171

Abstract:

Reinforcing fabrics or cords, particularly those made from adhesive activated (AA) polyester yarn, or non-adhesive activated (non-AA) polyester yarn, or aramid yarn, maybe coated in a first of two dips in a two-step (double-dip) process, or more preferably in a single-step (single-dip) process, with an adhesive dispersion comprising a solid finely divided reversibly blocked polyisocyanate (RBP), having a majority of its primary particles smaller than 1 micron in average diameter, when the RBP is held in suspension as a substantially homogeneous dispersion with the aid of a hydrocarbyl disperser. The RBP is so held with less agitation than is required to produce a vortex in the dispersion. There is no "flaking" on the fabric after it is dried at a temperature higher than 250. degree. F. for less than about 3 minutes, and heat-set at a temperature above that at which the RBP is unblocked.
