본 발명의 합성 폴리이소프렌 라텍스 에멀젼은 예비-가황처리 조성물 및 후-가황처리 조성물을 갖는다. 예비-가황처리 조성물은 아연 디티오카바메이트에 의해 촉매적으로 파괴되는 고급 S고리 구조를 갖는 가용성 황을 포함한다. 라텍스 에멀젼은 후-가황처리 경화 주기 동안 입자간 영역을 가교시키는 촉진제를 갖는 후-가황처리 조성물을 갖는다. 필름은 높은 인장 강도, 인장 계수, 전단 강도, 파열 압력 및 파열 부피를 나타낸다. A synthetic polyisoprene elastomeric condom comprises synthetic polyisoprene particles, intra-polyisoprene particle crosslinks and inter-polyisoprene particle crosslinks. The intra-polyisoprene particle crosslinks and the inter-polyisoprene particle crosslinks are substantially uniform in the synthetic polyisoprene condom.
