이중 결합 말단 기 작용화를 갖는 아크릴레이트-기반 올리고머는 자유 라디칼 중합에 의해 형성되는데, 여기서, 제1 단계에서, 아크릴레이트 성분 및 방향족 성분의 모노머 혼합물은 이작용성 조절제를 사용하면서 반응되며, 조절제의 양은 모노머 혼합물의 몰양 대 조절제의 몰양의 비가 100:20 내지 100:0.5인 방식으로 선택되며, 중합은 모노머 전환이 적어도 96%에 도달할 때까지 수행된다. 제2 단계에서, 얻어진 거대분자는 중합이 수행된 반응기에서, 작용기를 가지고 에틸렌성 이중 결합을 갖는 적어도 하나의 화합물 Z와 반응되며, 적어도, 에틸렌성 이중 결합을 함유한 화합물 Z의 일부는 화합물 Z의 작용기와 이작용성 조절제의 작용기들 중 하나의 반응을 통해 거대분자에 연결된다. Acrylate-based oligomers having double-bond end-group-functionalization are produced by means of free-radical polymerization where, in a first step, a monomer mixture of an acrylate component and an aromatic component is reacted with use of a difunctional regulator, the molar quantity of monomer mixture to that of regulator being from 100:20 to 100:0.5 and the polymerization is continued until monomer conversion reaches at least 96%. In a second step, the resultant macromolecules are reacted, in the reactor in which the polymerization was conducted, with at least one compound Z which has a functional group and has an ethylenic doule bond, and at least that portion of the compound Z that contains the ethylenic double bond becomes linked to the macromolecules via reaction of one of the functional groups of the difunctional regulator with the functional group of the compound Z.
