摘要： There is provided a kit comprising a first component comprising a first polyolefin and a polymerisable epoxide resin, wherein the first polyolefin is a major phase of the first component, and a second component comprising a second polyolefin and a catalytic agent. There is also provided a method of providing a polyolefin composite, the polyolefin composite comprising a first polyolefin, a polymerisable epoxide linker and a second polyolefin, the method comprising mixing a first component comprising a first polyolefin and a polymerisable epoxide resin, wherein the first polyolefin is a major phase of the first component; and a second component comprising a second polyolefin and a catalytic agent, to form a mixture, and processing the mixture to obtain the polyolefin composite.

摘要： A mechanically-enhanced polyolefin composite is provided. The mechanically-enhanced polyolefin composite comprises a matrix comprising a polyolefin, a polymer having a moiety grafted thereon, and a polymerisable linker, wherein the moiety grafted on the polymer is covalently bonded to the polymerisable linker via a chemical bond, and a filler disposed within the matrix. There is also provided a method of providing a polyolefin composite, comprising a matrix comprising a polyolefin, a polymer having a moiety grafted thereon, and a polymerisable linker, wherein the moiety grafted on the polymer is covalently bonded to the polymerisable linker via a chemical bond, and a filler disposed within the matrix, the method comprising (i) mixing a polyolefin, a polymer having a moiety grafted thereon, a polymerisable linker and a filler; (ii) melting the mixture of step (i); and (iii) kneading the mixture of step (ii).

摘要： According to the present disclosure, a method of forming an exfoliated or intercalated filler material is provided, wherein the said method comprises the steps of mixing particles of filler material such as montmorillonite (MMT), mica, layered double hydroxide (LDH), and attapulgite (AT) dispersed in an aqueous medium with cationic acrylate monomers to form modified particles comprising positively charged ions, dispersing the modified particles in organic medium to form a dispersion, contacting said dispersion with an organo-silicate such as tetraethyl orthosilicate (TEOS) and a functionalizing agent comprising an organo-silane such as aminopropyltrimethoxysilane (APTMS), in the presence of a basic catalyst to form a layer of silica on the modified particles. The present disclosure also relates to an exfoliated or intercalated filler material obtained by the said method as well as a method of forming a resin/clay nanocomposite.
