<p>A novel rubber compound comprises:
<UnorderedLists id="ula01" listStyle="none"><ListItem>(I) 100 parts by weight of a rubber component comprising
<UnorderedLists id="ula02" listStyle="none"><ListItem>(la) 40 to 100% by weight of an elastomeric copolymer composed of
<UnorderedLists id="ula03" listStyle="none"><ListItem>50% by weight or more of C<Sub>4</Sub> or C<Sub>5</Sub> conjugated diene,</ListItem><ListItem>styrene in an amount such that the amount in the elastomeric copolymer, (la), of the conjugated diene plus the styrene is 80 to 99.5% by weight, and 0.5 to 20% by weight of glycidyl-containing monomer provided that the amount of glycidyl-containing monomer in the rubber component, (I), is 0.5% by weight or more; and</ListItem></UnorderedLists></ListItem><ListItem>(lb) 60 to 0% by weight of a vulcanizable rubber;</ListItem></UnorderedLists></ListItem><ListItem>(II) 0.1 to 15 parts by weight of an amine salt of a carboxylic acid; and</ListItem><ListItem>(III) 0 to 7 parts by weight of sulphur.</ListItem></UnorderedLists></p><p>Such a rubber compound can readily be formulated whereby it does not undergo scorching at the time of processing and gives, when vulcanized (crosslinked), a vulcanized rubber having a high modulus of elasticity.</p> |
