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.
A copolymer comprising plural polyol monomeric units, said polyol monomeric units being acrylated and acylated or acetalized, wherein the acrylated and acylated or acetalized polyol monomeric units have an average degree of acrylation which is greater than 1, 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, wherein the copolymer has a linear or branched-chain structure, and wherein the copolymer has a molecular weight (Mn) of at least 1 KDa.
A copolymer comprising plural polyol monomeric units, said polyol monomeric units being acrylated and acylated or acetalized, wherein the acrylated and acylated or acetalized polyol monomeric units have an average degree of acrylation which is greater than 1, 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, wherein the copolymer has a linear or branched-chain structure, and wherein the polyol is selected from the group consisting of 1,2,4-butanetriol, glycerol, panaxatriol, panaxytriol, talose, balsaminol B, momordol, erythritol, enterodiol, xylitol, miglitol, sorbitol, mannitol, galactitol, isomalt, maltitol, aldohexose, aldopentose, aldotetrose, aldose, allose, altrose, arabinose, amylopectin, amylose, dextrose, erythrose, fructose, galactose, glucose, gulose, hexose, idose, ketohexose, ketose, lactose, lyxose, maltose, mannose, pentose, ribose, saccharose, sucrose, talose, tetrose, xylose, and stereoisomers thereof.
A copolymer comprising plural polyol monomeric units, said polyol monomeric units being acrylated and acylated or acetalized, wherein the acrylated and acylated or acetalized polyol monomeric units have an average degree of acrylation which is greater than 1, 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, wherein the copolymer has a linear or branched-chain structure, wherein the copolymer comprises plural polyol monomeric units, said polyol monomeric units being acrylated and acylated, and wherein the acrylated and acylated polyol monomeric units have an average degree of acrylation which is greater than 1, but less than the number of the hydroxyl groups of the polyol and have an average degree of acylation which is 1 or more, but less than the number of the hydroxyl groups of the polyol.
A copolymer comprising plural polyol monomeric units, said polyol monomeric units being acrylated and acylated or acetalized, wherein the acrylated and acylated or acetalized polyol monomeric units have an average degree of acrylation which is greater than 1, 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, wherein the copolymer has a linear or branched-chain structure, wherein the copolymer comprises plural polyol monomeric units, said polyol monomeric units being acrylated and acetalized, and wherein the acrylated and acetalized polyol monomeric units have an average degree of acrylation which is greater than 1, but less than the number of the hydroxyl groups of the polyol and have an average degree of acetalization which is 1 or more, but less than the number of the hydroxyl groups of the polyol.
