US Patent:

49945289, Feb 19, 1991

Filed:

Dec 14, 1989

Appl. No.:

7/450947

Inventors:

Tonson Abraham - Elyria OH
Philip H. Starmer - Avon Lake OH
August H. Jorgensen - Avon Lake OH

Assignee:

The B. F. Goodrich Company - Akron OH

International Classification:

C08F 804

US Classification:

525338

Abstract:

A random copolymer is formed by emulsion polymerization from two monomeric classes. The first monomeric class is a conjugated diene or substituted conjugated diene containing from four to about eight carbon atoms. The second monomeric class is of the general formula CH. sub. 2. dbd. CHR. sub. 1 CX wherein R. sub. 1 is hydrogen or an alkyl group containing from 1 to about 4 carbon atoms and X is --OOR. sub. 2, --ONR. sub. 3 R. sub. 4, or --OOR. sub. 7 OR. sub. 2. R. sub. 2 is an alkyl group containing from 1 to about 4 carbon atoms, --CH. sub. 2 CF. sub. 3 or --CH. sub. 2 CF. sub. 2 CF. sub. 2 H. R. sub. 3 and R. sub. 4 are alkyl groups independently containing from 1 to about 4 carbon atoms and R. sub. 7 is an alkylene group containing from 1 to about 4 carbon atoms. The second monomeric class can be replaced with up to about 20 percent by weight of the general formula ##STR1## wherein R. sub.

Assignee:

Zeon Chemicals USA, Inc. - Avon Lake OH

International Classification:

C08K 300

US Classification:

523334

Abstract:

High amounts of silicon dioxide are readily incorporated into an emulsion polymerized elastomer by mixing an aqueous dispersion of silicon dioxide with a latex of the emulsion polymer and subsequently spray drying the mixture. Free flowing, fine-size (e. g. , less than 500 micrometers) particles are produced with generally complete incorporation of silicon dioxide. The presence of the silicon dioxide permits rubbers with low gel and/or low Mooney viscosity to be spray dried whereas previously this could not be accomplished. Compared to conventional means of adding a silica to a bale rubber, the above powdered masterbatch gives shorter mixing times with lower power consumption with improved physical properties, such as tensile strength.

Filed:

Nov 10, 1975

Appl. No.:

5/630452

Inventors:

Philip Hubert Starmer - Avon Lake OH

Assignee:

The B. F. Goodrich Company - Akron OH

International Classification:

C08L 2328
C08L 4700

US Classification:

260888

Abstract:

Compositions comprised of a polymer blend of a halogen-containing polymer and a diene/nitrile rubber having active halogen cure sites are covulcanized using a common cure system. The halogen-containing polymers used in the polymer blend include the commercial polymers such as epihalohydrin polymers, polychloroprenes, fluoroelastomers, halogen-containing acrylates, and halogenated polyolefins. The curative ingredients employed are those normally used for the cure of the halogen-containing polymer employed in the polymer blend.

Appl. No.:

6/618702

Inventors:

Philip H. Starmer - Avon Lake OH

Assignee:

The B. F. Goodrich Company - Akron OH

International Classification:

C08K 511

US Classification:

524310

Abstract:

A preferred carboxylated nitrile rubber is prepared by polymerizing a diene, a nitrile and a small amount of an acrylic acid, which rubber has distributed therethrough an amount of alkyl or alkenyl monocitrate to obtain improved scorch time and reduced cure time.
