- 유동가능한 상태에서 투명한 유동가능한 중합체성 재료를 성형 장치의 성형용 캐비티(cavity) 중에서 연마 패드 형상으로 성형하는 단계,유동가능한 중합체성 재료를 성형용 캐비티의 투명부 형성 영역에서 냉각시켜, 상기 투명부 형성 영역에서의 중합체성 재료를 투명한 상태로 고화시키는 단계 및성형용 캐비티의 상기 투명부 형성 영역에 접하는 불투명부 형성 영역에서 중합체성 재료를 상기 투명부 형성 영역에서보다 느린 속도로 냉각시켜, 상기 불투명부 형성 영역에서의 중합체성 재료를 상기 투명부 형성 영역에서보다 불투명한 상태로 고화시키는 단계를 포함하는, 유리, 반도체, 유전성/금속 복합재 및 집적 회로의 연마에 유용한 연마 패드의 제조방법.
- 제35항에 있어서, 유동가능한 중합체성 재료가 단일 열가소성 재료이고, 투명부 형성 영역에서의 유동가능한 중합체성 재료의 냉각 단계가, 결정화 온도 미만의 온도로 냉각시켜 결정화를 최소화하고, 중합체를 실질적으로 무정형이고 투명한 상태로 유지시키는 단계를 추가로 포함하는 방법.
- 제35항에 있어서, 유동가능한 중합체성 재료가 단일 열가소성 재료이고, 투명부 형성 영역에서의 유동가능한 중합체성 재료의 냉각 단계가, 결정화 온도 미만의 온도로 냉각시켜, 단일 열가소성 재료를 너무 작아서 빛을 산란시킬 수 없는 미결정 크기로 고화시키는 단계를 추가로 포함하는 방법.
- 제35항에 있어서, 유동가능한 중합체성 재료가 혼화성 열가소성 재료들로 이루어진 블렌드이고, 투명부 형성 영역에서의 유동가능한 중합체성 재료의 냉각 단계가, 혼화성 열가소성 중합체를 상 분리된 비혼화성 중합체로 고화시켜 혼화성 열가소성 중합체의 상 분리를 억제하는 온도 미만으로 냉각시키는 단계를 추가로 포함하는 방법.
- 제35항에 있어서, 유동가능한 중합체성 재료가, 고화되어 상 분리된 마이크로-도메인(micro-domain)을 형성하는 반응성 열경화성 중합체이고, 투명부 형성 영역에서의 유동가능한 중합체성 재료의 냉각 단계가, 반응성 열경화성 중합체가 상 분리된 마이크로-도메인을 형성하는 온도 미만으로 냉각시키는 단계를 추가로 포함하는 방법.
- 제35항에 있어서, 상기 투명부 형성 영역 및 상기 불투명부 형성 영역에서의 유동가능한 중합체성 재료의 냉각이, 불투명부 형성 영역으로부터 투명부 형성 영역에 이르기까지 명확한 구조로 구성되지 않은 이행부(transition)를 형성하는 방법.
