Abstract

Coconut coir is the largest component in coconut (Cocos nucifera L.) which contains 75% fiber and 25% cork. Coconut fiber contains cellulose as much as 54.3% with α-Cellulose 26.6% α-Cellulose is a polymer that is widely used in human life. The molecular weight and degree of polymerization are important because they directly affect the chemical properties of the polymer. The purpose of this study is to determine the molecular weight and degree of polymerization of α-Cellulose by viscosity method. The results showed that the molecular weight and degree of polymerization of α-Cellulose of young coconut coir (Cocos nucifera L.) were 3.0841 x104 g/mol and 171, respectively.

Keywords: coconut α-cellulose molecular weight polymerization’s degree
