- •
DPNR-graft-PSMA was successfully prepared by the graft-copolymerization of SMA onto DPNR in latex stage.
- •
The highest conversion of 95 mol% and grafting efficiency of 62 mol% were obtained.
- •
The melting temperature, Tm and degree of crystallinity, w/w% increased after graft-copolymerization.
- •
The nanomatrix structure was formed and the highest stress at break of 13 MPa was achieved.
- •
The abrupt increase in the stress at strain 3 may be due to the nucleating effect of the crystallizable stearyl groups.
- •
The strain-induced crystallization of the DPNR-graft-PSMA is promoted by the effect of the PSMA.
