Cyanoethylated cellulose samples of different degrees of substitution (or nitrogen content) have been prepared and intrinsic viscosity has been measured which shows that cellulose undergoes no appreciable fall in molecular weight by this reaction. Powdered rubber wood (Hevea Brasiliensis) has been cyanoethylated in the same way as cellulose and the product (CRW) blended with HDPE both without and with maleic anhydride-grafted-HDPE as compatibilizer. Measurement of impact properties reveals that the use of a compatibilizer significantly increases the dispersion of CRW particles in the HDPE matrix and promotes ductile fracture and higher impact strength, while the effects of notrogen content of CRW on these properties are only marginal.
