摘要：
Skim natural rubber latex has been characterised before crosslinking with gamma-radiation. Micrographs of gamma-vulcanised skim particles embedded in polystyrene revealed a semi-interpenetrating polymer network morphology of fine rubber-polystyrene particles surrounded by membrane layer. Creamed skim latex was prepared by addition of 15-45 phr sodium alginate and further used for encapsulation of urea fertiliser. Non-spherical capsules containing an homogeneous urea dispersion were obtained. PRC/1571 (C) 1999 IoM Communications Ltd.
