Definitions
- Copolymer / polyolefin rubber blends through reactive processing with phenol-aldehyde condensate
- the present invention relates to blends of a copolymer and a polyolefin rubber which are obtainable by single-stage melt compounding and have very good mechanical properties, a process for their preparation and their use for the production of moldings.
- Copolymer / rubber blends are produced in order to achieve improvements in the mechanical properties of the corresponding materials compared to the pure components.
- rubber-modified thermoplastics or thermoplastic elastomers are obtained. Appropriate materials are used in the areas of household, electrical / electronics, automotive, medical technology.
- copolymer / rubber blends e.g. AES (SAN / EP (D) M blend
- AES SAN / EP (D) M blend
- radical copolymerization of styrene and acrylonitrile monomers takes place in the presence of dissolved or emulsified rubber.
- styrene-acrylonitrile copolymer chains are also grafted onto the rubber.
- graft copolymers act as phase mediators in the SAN / rubber blend and are necessary in order to achieve a morphology and phase binding of the rubber particles dispersed in the SAN matrix which are advantageous for the blend properties.
- a disadvantage of such processes is the need to remove the solvent or the emulsion medium, which is associated with a greater outlay in terms of process technology or the production of waste water.
- the SAN / rubber blend is produced without a solvent or emulsion medium above the glass transition or melt temperature of the components in a kneader or extruder.
- a phase mediator must also be available here. This phase mediator must either be added separately during the blend production or must be formed in situ during the blend production. The separate addition of a phase mediator has the disadvantage that it has to be synthesized in an upstream production step.
- the phase mediator can be produced in situ by using functionalized blend components which react with one another to form graft or block copolymers during the blend manufacture.
- functionalized blend components which react with one another to form graft or block copolymers during the blend manufacture.
- maleic anhydride-functionalized EPDM with NH 2 -functionalized SAN can be converted into SAN-EPDM graft copolymer, which acts as a phase mediator in the blend (described, inter alia, in C. Pagnoulle, R. Jerome, Polymer 2001, 42, 1893).
- the functionalized blend components have to be produced separately. The same applies to the method described in US-A 4,278,572.
- polyolefins are reacted with phenol-formaldehyde condensates (methylolphenol oligomers) in the presence of a Lewis acid to give methylolphenol-modified polyolefins.
- phenol-formaldehyde condensates methylolphenol oligomers
- a Lewis acid methylolphenol-modified polyolefins.
- EPDM phenol-formaldehyde condensates
- methylolphenol-modified polyolefins are then reacted with a second blend component to the desired blend in the next synthesis step.
- the disadvantage of this method is that two synthesis steps are required for producing the blend and that SAN / polyolefin rubber blends in which the polyolefin rubber contains at least one diene component, such as EPDM, cannot be produced in this way are.
- copolymer / polyolefin rubber blends can be obtained in only one synthesis step by melt mixing the copolymer and
- Polyolefin rubber with the addition of small amounts of a phenol-aldehyde condenser sats and a Lewis acid can be produced, commercially available, not separately functionalized copolymer and polyolefin rubber types can be used and also those polyolefin rubbers which contain a diene component (such as EPDM) can be used.
- the copolymer / polyolefin rubber blends produced in this way have significantly better mechanical properties than copolymer / polyolefin rubber blends which are produced without the addition of phenol-aldehyde condensate and Lewis acid.
- the present invention thus relates to copolymer / polyolefin rubber blends obtainable by compounding the following components:
