A phosphorus containing acrylate monomer has been constructed from isosorbide, a renewable biomaterial. Treatment of isosorbide with diphenylchlorophosphate generates a mixture of phosphorus esters from which -5-(diphenylphosphato)isosorbide-2--ol may be isolated using column chromatography. Conversion of the alcohol to the corresponding acrylate by treatment with acroyl chloride provides a reactive acryloyl monomer containing a diphenylphosphato unit. Copolymerization of this monomer, at levels to provide 1% or 2% phosphorus incorporation, with styrene generates a polymer with substantially diminished flammability compared to that for styrene homopolymer.
一种含磷丙烯酸酯单体由可再生生物材料异山梨醇构建而成。用二苯基氯磷酸酯处理异山梨醇会生成磷酸酯混合物，通过柱色谱法可从中分离出5-(二苯基磷酸酯)异山梨醇-2-醇。用丙烯酰氯处理该醇，将其转化为相应的丙烯酸酯，得到一种含有二苯基磷酸酯单元的活性丙烯酰单体。该单体与苯乙烯以能使磷含量达到1%或2%的比例进行共聚，生成的聚合物与苯乙烯均聚物相比，可燃性显著降低。
