Poly Ethylene

Sago starch is modified with 1 wt % Poly butyl acrylate (PBA) and Poly ethylene oxide (PEO) monomer and 1 wt% of initiator, potassium persulfate (PPS) at temperature 80°C for 2 hours. Modified sago starch is cooled under room temperature for 24 hours prior to Natural Rubber Latex (NRL) compounding process. Results indicates that NRL films with PBA modified sago starch have higher mechanical properties compared to PEO modified sago starch and unmodified sago starch. Swelling test indicates that PEO gives lowest percentage of swelling and crosslink density. This is due to higher reaction probability that produce more closely packed structure with NRL matrix compared to PBA which only improved the compatibility of sago starch particle with rubber matrix. Thus, chemically modified sago starches are preferable to be used as fillers to produce better interaction between fillers and rubber matrix.

Initial Viscosity

Aqueous solutions of a 1 weight-per cent poly (ethylene oxide) (PEO) were degassed under vacuum, transferred to a parallel plate viscometer under a nitrogen gas blanket, and exposed to Co60 gamma radiation. The Co60 source was rated at 4000 curies, and the dose ratewas 3.8x105 rads/hr. The poly (ethylene oxide) employed in the irradiations had an initial viscosity average molecular weight of 2.1 x 106.The solutions were gelled by a free radical reaction with dosages ranging from 5x104 rads to 4.8x106 rads.
