Clear thermoplastic compositions based on impact-resistant polymethylmethacaylat with improved heat stability. |
| 摘要 |
<p>The thermoplastic compositions include polymethyl methacrylate which has a percentage of syndiotactic triads which is higher than or equal to 70 % and a reinforcing additive of multilayer structure in which at least one of the layers consists of an acrylic elastomer. The compositions are transparent, impact-resistant and have an improved heat resistance.</p> |
