First Claim
1. A crosslinkable polymer system comprising (a) a main portion comprising a product Q formed from an aromatic ethylenically unsaturated moiety and a first reactive ethylenically unsaturated moiety wherein product Q provides carbon-carbon linkages in the backbone of said crosslinkable polymer system and a second reactive ethylenically unsaturated moiety at least partially reacted with said first reactive ethylenically unsaturated moiety of product Q, and (b) a first terminal moiety comprising a nitroxide containing group.

Abstract
The present invention provides a crosslinkable polymer system that can be crosslinked to form a wide variety of polymeric, copolymeric and oligomeric compounds. The crosslinkable system comprises a product Q formed from an aromatic ethylenically unsaturated moiety and a first reactive ethylenically unsaturated moiety, and a second reactive ethylenically unsaturated moiety at least partially reacted with the first reactive ethylenically unsaturated moiety, and a first terminal moiety comprising a covalently bonded nitroxide containing group.
