  • Filled hydrolyzable copolymer compositions resistant to premature crosslinking
    Patent number: 5312861
    Abstract: Improved filled silane copolymer compositions resistant to premature crosslinking during compounding and storage but which are readily hydrolyzed and undergo cure in the presence of silanol condensation catalyst are provided. The compositions are comprised of random copolymers of ethylene and vinyltriethoxysilane and contain relatively high levels of particulate fillers. Rubbery ethylene copolymers are included with the silane copolymer to produce compositions with superior physical properties. The invention also relates to the method of crosslinking these compositions by combining the filled silane copolymer compositions with a second component which has a silanol condensation catalyst dispersed in a polymer resin.
    Type: Grant

  • Hydrolyzable silane copolymer compositions resistant to premature crosslinking and process
    Patent number: 5266627
    Abstract: Filled, pelletized silane copolymer compositions resistant to premature crosslinking during compounding and storage but which are readily hydrolyzed and undergo cure in the presence of silanol condensation catalyst are provided. The compositions comprise random copolymers of ethylene an vinyltriethoxysilane with relatively high levels of particulate fillers, such as carbon black, alumina trihydrate and the like, dispersed therein. The invention also relates to a method of crosslinking these compositions by combining the filled silane copolymer composition with a second component containing a silanol condensation.
    Type: Grant
    Filed: July 15, 1992
    Date of Patent: November 30, 1993
    Assignee: Quantum Chemical Corporation
    Inventors: Craig C. Meverden, Robert L. Silverman
  • Water curable compositions of silane containing ole36in polymers
    Patent number: 4806594
    Abstract: A water curable composition comprising:(a) at least one polymer selected from the group consisting of silane grafted homopolymers of ethylene, propylene, or 1-butene; silane grafted copolymers wherein a major proportion thereof is attributed to an ethylene, propylene, or 1-butene monomer; and a copolymer wherein a major proportion thereof is attributed to an ethylene, propylene, or 1-butene monomer and a minor proportion thereof is attributed to silane, each polymer having at least one silane moiety containing at least one hydrolyzable group; and(b) at least one polysiloxane having the following formula: ##STR1## wherein R=C.sub.3 H.sub.6 (OC.sub.3 H.sub.6).sub.y (OC.sub.2 H.sub.4).sub.
