Seeking: Methods of attaching/grafting linear alpha-olefins onto PE, polyester elastomers, fluoros, and other polymers
Our client needs to functionalize polymers by grafting a linear aliphatic olefin to the polymer backbone. The polymers we’re working with include harder-to-functionalize materials — in particular polyethylene, fluoropolymers, and thermoplastic polyester elastomers (such as DuPont Hytrel®).
Our polymer applications often require high temperature resistance and high materials performance. Often, our polymers must perform at 150 degrees C, or even up to 280 C as in the case of polyethylenes.
We are particularly interested in grafting an aliphatic alpha-olefin to a thermoplastic polyester elastomer. The terminal double bond functional group must be retained in the final polymer.
There are several constraints on the solution technology:
- A dendromeric olefin would prohibit other processing we need to perform on the material.
- General high-temperature stability.
- Prefer no other functional group within six carbons of the olefin, but this is not a requirement.
- Prefer solutions that can generalize across polymers, but this also is not a requirement.
Although we may wish to manufacture small batches, ideally, we’d be able to purchase the olefin-grafted polymer from a secondary company that makes the material for us.
The olefin-containing polymer will be compounded into a formulation that will be made into components such as connectors, housings, and other moldable parts. This technology will allow for the formation of a more durable polymer in a secondary processing step, e.g. higher use temperature, abrasion resistance, increased stiffness.
