코폴리머 폴리올을 제조하는 방법은 (a) 10 wt% 내지 90 wt%의 고형 작용성 첨가제 성분을 10 wt% 내지 90 wt%의 폴리스티렌 성분과 화합시킴에 의해 사전-화합된 열가소성 폴리머 조성물을 형성하는 단계, (b) 상기 사전-화합된 열가소성 폴리머 조성물을 용융시켜 용융된 열가소성 폴리머 조성물을 형성하는 단계, (c) 안정제 성분의 존재에서 상기 용융된 열가소성 폴리머 조성물을 캐리어 폴리올 성분과 배합시켜, 상기 캐리어 폴리올 성분의 연속 상 내에 분산된 상기 사전-화합된 열가소성 폴리머 조성물을 포함하는 예비-혼합물을 형성하는 단계, 및 (d) 상기 예비-혼합물을 냉각시켜 코폴리머 폴리올을 형성하는 단계를 포함한다. A method for making a copolymer polyol includes (a) forming a pre-compounded thermoplastic polymeric composition by compounding from 10 wt % to 90 wt % of a solid functional additive component with from 10 wt % to 90 wt % of a polystyrene component, (b) melting the pre-compounded thermoplastic polymeric composition to form a melted thermoplastic polymeric composition, (c) combining the melted thermoplastic polymeric composition with a carrier polyol component in the presence of a stabilizer component to form a pre-mixture that includes the pre-compounded thermoplastic polymeric composition dispersed within a continuous phase of the carrier polyol component, and (d) cooling the pre-mixture to form the copolymer polyol.
