A method of producing a sliane cross-linked polyethylene is disclosed which includes maleating a polyethylene polymer to form a maleated polyethylene and reacting the maleated polyethylene with a primary or secondary amino silane to form a silane-grafted polyethylene. The method further includes treating the silane-grafted polyethylene in a moisture curing process to form the silane cross-linked polyethylene.

A preparation method of solvent-free self-emulsifying water-soluble chlorinated polypropylene is provided. By uniformly mixing chlorinated polypropylene, an acrylic acid/ester mixture and a cosolvent, initiating the chlorinated polypropylene to generate free radicals by using an initiator, further initiating free radical polymerization of the acrylic acid/ester mixture, then adding an isocyanate-terminal carboxyl hyperbranched polyester adduct, reacting, then neutralizing with amine, emulsifying, and diluting with deionized water, the solvent-free self-emulsifying water-soluble chlorinated polypropylene with a solid content of 30-45% may be obtained. The process of the present invention is simple, and easy to industrialize, and the product has the advantages of low VOC content, no organic solvent, water dilution, excellent stability, etc., and is expected to be widely used in the fields of water-soluble paints, surface modification of non-polar or low-polar plastics and the like.

The disclosure relates to the functionalization of a carbon-carbon backbone (CCB) polymer using a (cyclic) grafting agent, an initiator, and optionally a reversible radical trapping agent. The grafting agent and/or initiator can be particularly selected in terms of their surface energy and/or half-life, respectively, to limit or control undesirable effects associated with reactive melt-processing, such as excessive crosslinking, chain scission, or grafting agent homopolymerization, as well as to improve or control desirable effects associated with reactive melt-processing, such as improved relative graft uniformity or homogeneity on the CCB polymer. In some cases, the grafting agent can further include a functional group to impart some additional or new chemical or physical property to the CCB polymer. In some cases, the reactively melt-processed mixture includes two or more different polymers that are compatibilized via the grafting agent.
