Flame retardant polyolefin-type resin and preparation method as well as optic fiber cable using the same

A flame retardant grafted polyolefin resin, comprising:

• a reactive polyolefin having a functional group including a moiety selected from the group consisting of anhydrides, epoxies, carboxylic acids, ketones, and isocyanates;
• and
• a monomeric flame retardant agent including an amine group and containing at least one element selected from the group consisting of phosphorus, nitrogen, silicon, and sulfur, the at least one element comprising more than 10% by weight of the monomeric flame retardant agent;
• wherein the monomeric flame retardant agent is grafted to the reactive polyolefin through a reaction between the amine group and the functional group of the reactive polyolefin.

A flame retardant cable comprising:

• at least one communication element;
• a polymeric jacket that surrounds the at least one communication element;
• wherein the polymeric jacket is formed at least in part from a flame retardant grafted polyolefin resin comprising:
• a reactive polyolefin having a first functional group;
• and
• a monomeric flame retardant agent have a second functional group;
• wherein the monomeric flame retardant agent is grafted to the reactive polyolefin through a reaction between the first functional group and the second functional group.
