Abstract: A chain-extended silicone represented by the formula Each R1 independently represents H or a C1-C15 hydrocarbyl group. Each R2 independently represents H or a C1-C6 alkyl group. Each A independently represents a C1-C18 hydrocarbylene group, optionally substituted with up to 5 heteroatoms selected from the group consisting of O, N and S. Each Z independently represents a leaving group displaceable by a primary or secondary alkylamine. Each m independently represents an integer from 5 to 1000, inclusive. n represents an integer greater than or equal to two. The chain-extended silicone can be functionalized with aziridine groups. Methods of making the foregoing are also disclosed. Curable compositions, including a thermal gap filler, including the chain-extended silicone are also disclosed.
