Alpha olefin-diene copolymers |
| abstract |
Atactic copolymers derived from an alpha-olefin, optionally ethylene and a non-conjugated diene are provided. The units derived from the diene provide pendant groups having internal or terminal double bonds. Suitable dienes for preparing such copolymers include: CH 2 ═C(R 1 )—R 2 —C(R 3 )═CH 2 , CH 2 ═C(R 1 )—R 4 —C(R 3 )═CH—CH 3 , wherein R 1 and R 3 are indenpendently selected from hydrogen or an alkyl group, R 2 and R 4 are alkylene moieties having a chain length of at least 3 carbon atoms and at least 1 carbon atom respectively, or a diene having a cyclic ring with one strained ring double bond and a substituent on the ring of the Formulae: ═CR 5 R 6 , —CR 7 ═CH 2 , wherein R 5 and R 6 and R 7 are independently selected from hydrogen or a C 1 -C 3 alkyl. Also provided are processes for the functionalisation of the atactic copolymers and their use as lubricating oil additives. |
