  The preparation of epoxi-des is easy and because of their ring strain they are capable of reacting with various nucleophiles to afford 1,2-difunctional products. Among these, 1,2-diols and 1,2-diacetoxy esters (1,2- diacetates) possess valuable synthetic utilities. Ordinarily, nu-cleophilic ring opening of epoxides with water in the presence of Lewis or Bronested acids leads to 1,2-diol products, and

  环氧化物的制备很容易，并且由于它们的环应变，它们能够与各种亲核试剂反应以提供 1,2-双功能产物。其中，1,2-二醇和1,2-二乙酰氧基酯（1,2-二乙酸酯）具有有价值的合成用途。通常，在路易斯酸或布朗斯台德酸存在下，环氧化物与水的亲核开环会产生 1,2-二醇产物，随后通过乙酰氯的乙酰化产生 1,2-二乙酰氧基酯。在一种简单的方法中，环氧化物可以在促进剂存在下与乙酸酐直接转化为 1,2-二乙酸酯。由于 1,2-二乙酰氧基酯的合成用途，特别是用于保护 1,2-二醇，

  The present invention relates to a homopolymer, copolymer, block copolymer, and statistical copolymer comprising plural polyol monomeric units. The polyol monomeric units being acrylated and acylated or acetalized. The acrylated and acylated or acetalized polyol monomeric units have an average degree of acrylation which is 1 or more, but less than the number of the hydroxyl groups of the polyol and have an average degree of acylation or acetalization which is 1 or more, but less than the number of the hydroxyl groups of the polyol. The present invention also relates to a method of making the homopolymers, copolymers, block copolymers, and statistical copolymers, and using them in various applications, such as asphalt rubber modifiers, adhesives, or an additive in a fracking fluid for oil fracking.
