聚甲基丙烯酸甲酯-聚丙烯酰胺嵌段共聚物的合成与表征
摘要:
利用4,4'-偶氮二[4-氰基戊酰(对-二甲基氨基)苯胺](ACPDA)多官能团引发剂中的偶氮基团,先在70℃分解引发甲基丙烯酸甲酯聚合,得到含有N,N-二甲苯胺端基的预聚物,它与过氧化苯甲酰组成氧化还原体系引发另一单体丙烯酰胺聚合,得到聚甲基丙烯酸甲酯-聚丙烯酰胺嵌段共聚物.产物用IR、PGC、TG、DTA、SEM等技术作了表征.所得产物具有嵌段共聚物的特征,其热稳定性优于聚甲基丙烯酸甲酯均聚物.

Synthesis and Characterization of Poly(methyl methacrylate)-b-Polyacrylamide
Abstract:
The preparation of poly(methyl methacrylate)-b-polyacrylamide(PMMA-b-PAAM) using 4,4'-azobis[4-cyanopentanoyl(p-dimethyl amino) anilide](ACPDA) as an initiator was investigated. At 70℃, ACPDA initiated methyl methacrylate(MMA) to give a PMMA prepolymer containing N,N dimethyl anilide terminal group(DMA). The redox system of the PMMA/benzoyl peroxide(BPO) could initiate the polymerization of acrylamide(AAM) to give PMMA-b-PAAM. The block copolymer was characterized by IR, TG, DTA, PGC and SEM. The PMMA-b-PAAM showed a better thermal stability than PMMA homopolymer.
