The hydrogenated vinyl-polybutadienes according to the present invention have degrees of hydrogenation of from 20 to 100%, Mooney viscosities in the range of from 10 to 150 Mooney units (ML 1+4/100° C.), glass transition temperatures (T<SUB>g</SUB>) of <=-57° C. and enthalpies of fusion (DeltaH) of <=30 J/g and having a microstructure with a) from 0 to 44 wt. % 1,2-vinyl-butadiene units of the formula b) from 20 to 64 wt. % 1,2-butylene units of the formula c) from 0 to 60 wt. % 1,4-butenylene units of the formula <?in-line-formulae description="In-line Formulae" end="lead"?><img id="PRIVATE-USE-CHARACTER-00001" he="7.20mm" wi="8.47mm" file="US07176262-20070213-Parenopenst.TIF" alt="private use character Parenopenst" img-content="character" img-format="tif" />CH<SUB>2</SUB>-CH-CH-CH<SUB>2</SUB><img id="PRIVATE-USE-CHARACTER-00002" he="6.77mm" wi="8.47mm" file="US07176262-20070213-Brketclosest.TIF" alt="private use character Brketclosest" img-content="character" img-format="tif" /><?in-line-formulae description="In-line Formulae" end="tail"?> and d) from 0 to 60 wt. % 1,4-butylene units of the formula <?in-line-formulae description="In-line Formulae" end="lead"?><img id="PRIVATE-USE-CHARACTER-00003" he="7.20mm" wi="8.47mm" file="US07176262-20070213-Parenopenst.TIF" alt="private use character Parenopenst" img-content="character" img-format="tif" />CH<SUB>2</SUB>-CH<SUB>2</SUB>-CH<SUB>2</SUB>-CH<SUB>2</SUB><img id="PRIVATE-USE-CHARACTER-00004" he="6.77mm" wi="8.47mm" file="US07176262-20070213-Brketclosest.TIF" alt="private use character Brketclosest" img-content="character" img-format="tif" /><?in-line-formulae description="In-line Formulae" end="tail"?> are outstandingly suitable for the production of rubber molded bodies of any kind, especially for the production of industrial rubber articles and of tires and tire components. The rubber molded bodies produced from the hydrogenated vinyl-polybutadienes according to the present invention have good resistance to ageing and good elasticity at low temperatures. |
