  • Patent number: 10759886
    Abstract: Disclosed are methods for the production of polymers, including random copolymers (RCPs), in single reactor gas or slurry phase polymerization processes, and polymer compositions produced therefrom. The methods enable polymers having low melting temperatures to be made in gas and slurry phase polymerization processes, where they conventionally could not be made in these processes due to stickiness and fouling problems in the reactor.

  • Patent number: 8080605
    Abstract: Polymer-filler coupling compounds with the formula B-A-Sx—N are claimed. In these compounds, B is an azaheterocyclic oxygen or sulfur containing moiety, or an allyltin moiety; Sx is a polysulfide, where x is between 2 and about 10; A is a linking atom or group that forms a bridge between B and Sx; and N is a blocking group. Sx can be a disulfide. N can be a conventional blocking group or other group such as -A-B. Methods for using the polymer-filler coupling compounds to modify polymers containing unsaturated carbon-carbon bonds and promote filler dispersion are also claimed. Additionally, vulcanizable rubber compositions containing the polymer-filler coupling compounds and methods for making vulcanized rubber compositions using the polymer-filler coupling compounds are also claimed.

  • Patent number: 7750085
    Abstract: A water-absorbing agent according to the present invention includes water-absorbent resin particles having an internal cross-linked structure, wherein a vicinity of a surface of the water-absorbent resin particle is cross-linked with a surface cross-linking agent, and the water-absorbent resin particle has therein a sea-island structure having (i) part containing a first water-soluble multivalent metal salt such as aluminum sulfate and (ii) part not containing the first water-soluble multivalent metal salt. With this arrangement, it is possible to provide a water-absorbing agent having less water-soluble component content, more excellent liquid permeability, and more excellent water retention under pressure than the conventional water-absorbing agent.
