Document Type and Number:
Japanese Patent JP5179036
Kind Code:
B2
Abstract:
In curable compositions (I) containing carboxylated elastomer(s) (II), polyvalent metal alpha ,beta -unsaturated carboxylate(s) and crosslinker(s) acting as free radical donor, (II) has Mooney viscosity (ML 1+4 at 100[deg]C) in the 1-35 range, measured to ASTM 1646; and (I) has complex viscosity over 30000 Pas at 60[deg]C and 10% amplitude, with amplitude-dependent change (ratio at 10%/100%) over 1.4 at 60[deg]C and under 1.5 at 130[deg]C; and temperature-dependent change (at 60/130[deg]C) over 6 measured in RPA 2000 (RTM: rubber process analyzer) at 1 Hz. In curable compositions (I) containing (1) elastomer(s) (II) with carboxyl and/or carboxylate group(s), (2) salt(s) of formula (III) and (3) crosslinker(s) (IV) acting as free radical donor, the novel features are that the elastomer or mixture of all elastomers used has a Mooney viscosity (ML 1+4 at 100[deg]C) in the 1-35 range, measured to ASTM 1646; and, measured in a RPA 2000 (RTM: rubber process analyzer) at 1 Hz, (I) has complex viscosity eta * over 30000 Pas at 60[deg]C and 10% amplitude, with amplitude-dependent change (ratio at 10%/100% amplitude) over 1.4 at 60[deg]C and under 1.5 at 130[deg]C; and temperature-dependent change (at 60/130[deg]C) over 6: (R(y&-)) x / yM(x&+) (III); R(y&-) : an alpha ,beta -unsaturated 3-14 C carboxylate containing y carboxylate groups; y : 1, 2, 3 or 4; x : 2, 3 or 4; M : a di-, tri- or tetravalent metal . Independent claims are included for (1) production of curable compositions (I); (2) production of cured elastomers from the composition; (3) the resultant cured elastomers.
