Title (EN) AMORPHOUS POLYOLEFINS
(FR) POLYOLEFINES AMORPHES
Abstract:
(EN) Amorphous polyolefins include units from acyclic mono-olefins, particularly ethylene, and units derived norbornene type olefins including units of formula (I), where: n1 is 0, 1 or 2, n2 is 0 or 1 and n1 + n2 > 0; n3 is 0 or from 1 to 4; n4 is 0 or from 1 to 4; R1, R2 and R3 are each hydrogen, halogen, alkyl, cycloalkyl, aralkyl, alkaryl or aryl; the ring group A1 is 1,2-cyclohexylene or a 1,2-phenylene which may be unsubstituted or substituted with halogen, alkyl or aryl and may have further 1,2-cyclohexylene or 1,2-phenylene fused to it. The polymers can be made by polymerisation of the monomers under Ziegler-Natta catalysis. They are amorphous and transparent having high Tg's and are useful in optical components such as optical discs.
(FR) Des polyoléfines amorphes comprenant des unités dérivées de mono-oléfines acycliques, en particulier l'éthylène, et des unités dérivées d'oléfines du type norbornène comprenant des unités de la formule (I), où n1 représente 0, 1 ou 2, n2 représente 0 ou 1 et n1 + n2 > 0; n3 représente 0 ou de 1 à 4; n4 représente 0 ou de 1 à 4; R1, R2 et R3 représentent chacun hydrogène, halogène, alkyle, cycloalkyle, aralkyle, alkaryle ou aryle; le groupe cyclique A1 représente 1,2-cyclohexylène ou un 1,2-phénylène qui peut être non substitué ou substitué par un halogène, alkyle ou aryle et peut en outre incorporer du 1,2-cyclohexylène ou du 1,2-phénylène. Les polymères peuvent être produits par la polymérisation des monomères sous catalyse Ziegler-Natta. Ils sont amorphes et transparents, présentent des températures de transformation élevées et sont utiles dans des composants optiques tels que des disques optiques.
