Abstract
(EN) A composition including an isocyanate compound and a block copolymer. The block copolymer has a number average molecular weight of 3000 to 20000. The block copolymer is an AB-type block copolymer including a hydrophilic segment A and a hydrophobic segment B. The hydrophilic segment A includes an end-capped polyoxyalkylene group. The hydrophobic segment B includes a copolymer of a hydrophobic monomer and a monomer having an active-hydrogen-containing group that is reactive with isocyanate. The block copolymer has a hydroxy value of 3 to 25 mg/gKOH.
(FR) L'invention concerne une composition comprenant un composé isocyanate et un copolymère séquencé. Le copolymère séquencé présente un poids moléculaire moyen en nombre compris entre 3000 à 20000. Le copolymère séquencé est un copolymère séquencé de type AB comprenant un segment hydrophile A et un segment hydrophobe B. Le segment hydrophile A comprend un groupe polyoxyalkylène à extrémité coiffée. Le segment hydrophobe B comprend un copolymère constitué d'un monomère hydrophobe et d'un monomère doté d'un groupe contenant de l'hydrogène actif qui réagit avec l'isocyanate. Le copolymère séquencé présente un indice d'hydroxyle compris entre 3 et 25 mg KOH/g.
