| 摘要 |
The present invention depicts the preparation process of methyl polymethacrylate whose structure of the polymer chains consists in blocks with structural sequences predominantly sindiotactic, in terms of syndiotactic pentads, alternated with blocks with structural sequences predominantly isotactic, in terms of isotactic pentads. Said methyl polymethacrylate is a semi-crystalline polymer, the melting peak temperature of its crystalline phase is registered in the interval of temperatures ranging between 200°C and 270°C.
