본 발명은 압출기에서, 라디칼 발생제에 의해 광화학적으로 파장 > 0.1 ㎛를 사용하여 가교되고/거나 열화학적으로 가교되었고, 히드록실 기를 함유하며, 폴리부타디엔/아크릴로니트릴 공중합체 (NBR)를 기재로 하는 하나 이상의 마이크로겔 (B)을 폴리비닐 클로라이드 (PVC)에 혼합함으로써 수득가능한 조성물, 상기 조성물의 제조 방법, 열가소적으로 가공가능한 투명한 성형품을 제조하는데 있어서의 상기 조성물의 용도, 및 상기 조성물로부터 제조된 성형품에 관한 것이다. The present invention relates to a composition obtainable by mixing to incorporate at least one microgel (B) that has been crosslinked by means of free-radical generators photochemical by using a wavelength>0.1 μm and/or thermally and that contains hydroxy groups and that is based on polybutadiene-acrylonitrile copolymers (NBR) into polyvinyl chloride (PVC) in an extruder, to processes for production thereof and to use thereof for reproduction of transparent thermoplastically processable molded items, and also to molded items produced from the said compositions.
