Abstract
(EN)
A block copolymer (A) having a first segment and a second segment, wherein the first segment is a polymer segment formed by a monomer component comprising a specific hydroxyl group-containing monomer and a specific polycyclic aliphatic hydrocarbon group-containing monomer, the second segment is a polymer segment formed by a monomer component comprising a specific long-chain alkyl group-containing monomer, and the content ratios of the monomers are specified amounts in all of the monomer components that form the block copolymer (A). The block copolymer enables the preparation of a release agent composition having a satisfactory usable time even when a crosslinking agent is used, and therefore enables the production of a release sheet having excellent releasability and hardness.
(FR)
L'invention concerne un copolymère séquencé (A) comportant un premier segment et un second segment, le premier segment étant un segment polymère formé par un constituant monomère comprenant un monomère spécifique contenant un groupe hydroxyle et un monomère spécifique contenant un groupe hydrocarboné aliphatique polycyclique, le second segment étant un segment polymère formé par un constituant monomère comprenant un monomère spécifique contenant un groupe alkyle à longue chaîne et les rapports de teneur des monomères étant des quantités spécifiées dans tous les constituants monomères formant le copolymère séquencé (A). Le copolymère séquencé permet la préparation d'une composition d'agent de décollement à délai satisfaisant d'utilisation, même en cas d'utilisation d'un agent de réticulation, et permet donc la production d'une feuille de décollement à excellentes aptitude au décollement et dureté.
(JA)
第1セグメントと第2セグメントを有するブロック共重合体(A)であって、前記第1セグメントは、特定の水酸基含有モノマーおよび特定の多環式脂肪族炭化水素基含有モノマーを含むモノマー成分により形成される重合体セグメントであり、前記第2セグメントは、特定の長鎖アルキル基含有モノマーを含むモノマー成分により形成される重合体セグメントであり、前記ブロック共重合体(A)を形成する全モノマー成分中、上記の各モノマーの割合が特定量であるブロック共重合体。当該ブロック共重合体は、架橋剤を使用した場合においても、良好な可使時間を有する剥離剤組成物を調製でき、かつ優れた剥離性および硬度を有する剥離シートを作製できる。
