摘要:
在85 ℃条件下, 用过氧化苯甲酰为引发剂, 在溶液中进行了苯乙烯(S t) 和甲基丙烯酸十二氟庚酯(G04) 共聚合反应 的研究, 合成出不同组成的无规共聚物(PS F)。采用1H NMR 对PS F 的组分进行分析, 通过Fineman -Ross 方程, 在低转化 率下(小于10 %) 测出S t (M 1) 和G04 (M 2) 的竞聚率, 得到r 1 =0.17 , r2 =0.84 。不同组成的PSF 的玻璃化转变温度(tg) 都比无规PS 的tg 低, 且随着G04 含量的增大, PS F 的t g 逐渐降低, 当n (St) ∶n (G04) =0.291 ∶1 时, PS F 的t g 为 60.4 ℃。
Abstract:
Sty rene (St) and dodecaf luo roheptyl me thacry late (G04)w ere copolymerized in solutio n at 85 ℃, using benzoy l pe ro xide (BPO)as initiato r .The random copolymer (PSF)of dif ferent co nsti tuent w as o btained .1H NMR w as used to analy ze the consti tuent s of PSF , and Fineman -Ro ss equation w as used for calculating monomer reactivi ty ratio s .From relevant feed monomer composi tion and copolymer compo sitio n , mo nomer reactivity ra tios r1 =0.17 (S t), r2 =0.84 (G04)were obtained .The glass t ransition temperature (tg )o f PSF decreased compared wi th that o f atactic po ly sty rene .With an increase o f the content o f G04 , t g of PSF decreases g radually , and w hen n (St) ∶n (G04) =0.291 ∶1 , the tg o f PSF is 60.4 ℃。
