Depression of the glass transition temperature of polyolefins containing cyclic monomers |
| abstract |
Copolymers of ethylene and a cyclic olefin, preferably a fused ring cyclic olefin (FRCO), optionally containing an alpha-olefin and/or a non-conjugated diene, display increasing glass transition temperatures (Tg) as the amount of FRCO in the copolymer increases. This increase brings these polymers quickly above a Tg acceptable as elastomers. Addition of specially selected process oils, based on cohesive energy densities of both the copolymer and the process oil, is shown to lower Tg to a range acceptable for elastomers e.g. below about -30 DEG C. The copolymer/process oil combination can then be used in elastomer compounding operations and behave in typical elastomer fashion. |
