US Patent 9394442 Hybrid thermoplastic gels and their methods of making

Methods, compositions, and systems are provided for a hybrid thermoplastic gel or sealant. The methods comprise providing (a) a styrenic block copolymer, (b) a Si-vinyl polymer, (c) heat, and optionally (d) an initiator, and reacting the styrenic block copolymer, Si-vinyl polymer, and optional initiator in the presence of the heat to form the hybrid thermoplastic gel. The gel composition may comprise 5-70 wt. % of a styrenic block copolymer, 60-95 wt. % of a Si-vinyl polymer, and 0-10 wt. % of an initiator. A closure or interconnect system may comprise a housing, a cable, and a hybrid thermoplastic gel made by reacting a styrenic block copolymer and a Si-vinyl polymer in the presence of heat.
