SOFT THERMOPLASTIC ELASTOMER COMPOSITION |
摘要 |
<p>The present invention relates to a soft, semicrystalline, thermoplastic elastomer composition which is comprised of (I) a hydrophobic thermoplastic block copolymer which is comprised of (I) the reaction product of (1) a hydrophobic polyol or polyamine, (2) a polyisocyanate or an aromatic dicarboxylic acid, and (3) a chain extender containing 2 to 20 carbon atoms, or the reaction product of (1) a hydrophobic polyol or polyamine, and (2) a carboxyl terminated telechelic polyaminde sequence; wherein the hydrophobic polyol or polyamine has a number average molecular weight in the range of from 1,000 to 4,000 Daltons; wherein the hydrophobic thermoplastic block copolymer has a weight average molecular weight in the range of 50,000 to 1,000,000 Daltons; and (II) from 1 to 80 weight percent of a mineral oil, wherein the soft, semicrystalline, thermoplastic elastomer composition has a Shore A hardness which is within the range of 20 to 80.</p> |
