    • The present invention is a process to make a composition comprising a block copolymer A-B and optionally a monovinylaromatic polymer, said process comprising: a) forming a mixture comprising: one or more cyclic component polymerizable by ring-opening polymerization (ROP) dispersed in at least one monovinylaromatic monomer, optionally a rubber dissolved in the monovinylaromatic monomer, b) contacting the mixture of step a) with a mixture of b1 and b2 such that: b1) is M[N(SiR8 3 ) 2 ] x in which M is a metal, R 8 is an hydrocarbon group and x is the valency of the metal M, or a metal alkoxide M(OR 9 ) x in which M is a metal, R 9 is an hydrocarbon group and x is the valency of the metal M, or phenol-based pro-ligands of formula (I) or a mixture thereof, or triazabicyclodecene (TBD), or a single-site metal catalyst component based upon a bulky β-diiminate ligands (BDI), represented by the general formula (II), b2) a functional alcohol containing, besides its -OH function, another functionality Y enabling the growth or the grafting of a polyvinylaromatic, c) polymerizing the solution obtained at step b) optionally in the presence of a free radical initiator, optionally in the presence of chain transfer agents, at conditions effective to produce: a monovinylaromatic block polymer B linked to the block polymer A by the aforementioned functionality Y such that H-A-O-R-Y-B or H-A-O-R-B-Y (referred in both cases as A-B to simplify) in which R is a linking group, optionally a monovinylaromatic polymer.
    • 本发明是一种制备包含嵌段共聚物AB和任选的单乙烯基芳族聚合物的组合物的方法,所述方法包括:a)形成混合物,其包含:至少分散在开环聚合(ROP)中可聚合的一种或多种环状组分 一种单乙烯基芳族单体,任选地溶解在单乙烯基芳族单体中的橡胶,b)使步骤a)的混合物与b1和b2的混合物接触,使得:b1)是M [N(SiR83)2] x,其中M是金属 ,R 8为烃基,x为金属M或金属醇盐M(OR 9)x的化合价,其中M为金属,R 9为烃基,x为金属M的化合价,或苯酚 - 基于由通式(II)表示的体积大的β-二亚胺配体(BDI)的单位点金属催化剂组分,或通式(I)表示的基于式(I)的前体配体或其混合物或三氮杂双环十碳烯(TBD) )除了-OH官能团之外还含有另一功能Y的官能醇 使得可以生长或接枝聚乙烯基芳族化合物,c)任选地在自由基引发剂存在下,任选地在链转移剂存在下聚合步骤b)获得的溶液,在有效产生单乙烯基芳族嵌段聚合物B 通过上述官能度Y与嵌段聚合物A连接,使得HAORYB或HAORBY(在两种情况下称为AB简化),其中R为连接基团,任选为单乙烯基芳族聚合物。
