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.
本发明涉及一种由多个多元醇单体单元组成的均聚物、共聚物、嵌段共聚物和统计共聚物。多元醇单体单元经丙烯化和酰化或缩醛化。丙烯化和酰化或缩醛化的多元醇单体单元的平均丙烯化程度为 1 或以上,但小于多元醇羟基的数目,其平均酰化或缩醛化程度为 1 或以上,但小于多元醇羟基的数目。本发明还涉及一种制造均聚物、共聚物、嵌段共聚物和统计共聚物的方法,以及将它们用于各种用途的方法,例如沥青橡胶改性剂、粘合剂或用于石油压裂的压裂液添加剂。
