  • Vinyl-modified nanofillers as interfacial compatibilizers and method for producing compatibilized polymer blends
    Patent number: 12012502
    Abstract: The present disclosure is related to the field of polymer processing, and, in particular, to a vinyl-modified nanofiller interfacial compatibilizer and a method for producing a compatibilized polymer blend. Vinyl-modified nanofillers can be used together with an initiator as a compatibilizer for polymer blends. The initiator can initiate a free radical reaction between the chains of the polymers in the blend and the vinyl groups on the surface of the vinyl-modified nanofiller, leading to in situ formation of a co-crosslinked polymer and thus compatibilization of the blend as well as improved tensile strength and modulus thereof. Results of examples showed that vinylsilane grafted onto the surface of the vinyl-modified nanofiller makes it possible for the nanofiller to be used as an effective compatibilizer. The vinyl-modified nanofillers can be used as a compatibilizer for various polymer blends systems.
