| 20080300367 | Impact modification and functionalization of copolymers of olefins and dienes - Disclosed is the preparation of compositions which are mixtures of certain types of epoxidized rigid copolymers of α-olefins and diene-derived co-monomers in combination with elastomeric diene-based polymers or copolymers. These two types of rigid and elastomeric polymeric materials are placed in a common liquid reaction medium and contacted therein with an oxidizing agent. The oxidizing agent, which can be a peroxide or peracid, epoxidizes in-situ at least a portion of the residual double bonds of the rigid copolymer and preferably also introduces hydroxyl groups, e.g., diol moieties, (or derivatives thereof such as ester groups) onto the unsaturated moieties of the elastomeric diene-based polymers or copolymers. This combination of materials which has been oxidized in-situ can then be co-precipitated to form a polymeric mixture which can be melt-molded into polyolefin materials of improved structural, thermal and mechanical properties with desirable impact resistance. | 12-04-2008 |
| 20080306215 | Functionalization of olefin/diene copolymers - A process is described for functionalizing a copolymer comprising units derived from at least one α-olefin and units derived from at least one diene, which copolymer contains at least one double bond. The process comprises reacting the copolymer with at least one functionalizing agent to introduce polar pendant oxygen-containing functional groups onto the copolymer. | 12-11-2008 |
