ABSTRACT

Polyvinyl benzyl chloride (PVBC) was synthesized by free radical polymerization of 4-vinylbenzyl chloride using benzoyl peroxide initiator at 60 ℃. PVBC was synthesised in different solvents such as toluene, xylene, 1,4-dioxane, and tetrahydrofuran. The polymers were structurally characterized by 1H NMR and FTIR spectroscopic techniques. The thermal property of the polymer was investigated by thermogravimetric analysis (TGA) and differential thermogravimetric analysis (DTA). The number average molecular weight, weight average molecular weight and polydispersity index of PVBC synthesised in different solvents were determined and compared by gel permeation chromatography technique.

 

Keywords: Polymer synthesis; polyvinyl benzyl chloride

 

ABSTRAK

Poli vinilbenzil klorida (PVBC) disintesis melalui pempolimeran radikal bebas daripada 4-vinilbenzil klorida dengan menggunakan pemula benzoil peroksida pada 60 ℃. PVBC disintesis dalam pelarut yang berbeza seperti toluena, xilena, 1,4-dioksana dan tetrahidro furan. Pencirian struktur polimer dibuat menggunakan teknik spektroskopi 1H NMR dan FTIR. Sifat terma polimer dikaji menggunakan analisis termogravimetrik (TGA) dan analisis termogravimetrik pembezaan (DTA). Berat molekul purata nombor (Mn), berat molekul purata berat (Mw) dan indeks polisebaran PVBC disintesis dalam pelarut berbeza telah ditentukan dan dibandingkan dengan teknik kromatografi penelapan gel (GPC).

 

Kata kunci: Poli vinilbenzil klorida; sintesis polimer
