POLYURETHANES WITH IMPROVED TEAR PROPAGATION RESISTANCE
Disclosed are polyurethanes formed from (A) a polyol component containing dimeric diol and/or trimeric triol and/or a polyether containing dimeric diol units and/or a polyester with OH-terminal groups formed from polcarboxylic acids, preferably dimeric fatty acids or trimeric fatty acids and diols;...

| description | Disclosed are polyurethanes formed from (A) a polyol component containing dimeric diol and/or trimeric triol and/or a polyether containing dimeric diol units and/or a polyester with OH-terminal groups formed from polcarboxylic acids, preferably dimeric fatty acids or trimeric fatty acids and diols; and (B) an isocyanate component containing prepolymers obtainable from the reaction between polyfunctional isocyanates and dimeric diol and/or trimeric triol and/or a polyether containing dimeric diol units and/or a polyester with OH-terminal groups formed from polycarboxylic acids, preferably dimeric fatty acids or trimeric fatty acids and diols; at least one of the components (A) and (B) contain dimeric or trimeric fatty acid or dimeric or trimeric fatty alcohol. The proposed polyurethanes have excellent resistance to tear propagation. |
