Aspects herein relate to biocompatible polyisobutylene-fiber composite materials and related methods. In one aspect a biocompatible composite material is included. The biocompatible composite material can include a network of fibers comprising one or more polymers to form a substrate and a continuous polyisobutylene matrix that is non-porous and completely surrounds the electrospun fibers. Other aspects are included herein.

A flame-retardant film formed from a resin composition without halogens and a decoration material film manufactured therefrom are provided. The resin composition includes: 12 wt % to 55 wt % of a first polyolefin resin, 20 wt % to 60 wt % of a second polyolefin resin, 3 wt % to 15 wt % of a phosphorus compound with spiro structure, and 15 wt % to 30 wt % of a flame retardant mixture. A phosphorus atom content of the first polyolefin resin ranges from 0.1 wt % to 1.0 wt %. The second polyolefin resin includes a polyethylene and a polypropylene. The flame retardant mixture includes a phosphorus-based flame retardant and further includes at least one selected from the group consisting of a nitrogen-based flame retardant, a silicon-based flame retardant, a boron-based flame retardant, and an inorganic metal flame retardant.

A composition comprising an ethylene/alpha-olefin interpolymer that comprises the following properties: a) a total unsaturation/1000C0.30; b) a molecular weight distribution (MWD)3.0; c) a TGIC broadness parameter B.sub.1/48.0. A solution polymerization process to prepare an ethylene/alpha-olefin/interpolymer, said process comprising polymerizing, in one reactor, at a reactor temperature 150 C., a reaction mixture comprising ethylene, an alpha-olefin, a solvent, and a metal complex as described herein. A method to determine the TGIC broadness parameter B.sub.1/x of a polymer composition comprising one or more olefin-based polymers.
