The present invention relates to a thermoplastic copolymer, block copolymer, and statistical copolymer comprising plural acrylated polyol monomeric units having different degrees of acrylation of hydroxyl groups. The acrylated polyol monomeric units have an average degree of acrylation greater than 1 and less than the number of the hydroxyl groups of the polyol. The present invention also relates to a method of making the thermoplastic copolymer, block copolymer, and statistical copolymer, and using them in various applications, such as asphalt rubber modifiers, adhesives, or an additive in a fracking fluid for oil fracking.

The present invention relates to a method of producing an improved asphalt. The method involves providing an asphalt and providing a compound of formula (I), as described herein. The asphalt is mixed with the compound of formula (I) under conditions effective to produce an improved asphalt. Also disclosed are an asphalt product and a method of making asphalt material. The invention further discloses a method of producing an improved asphalt comprising providing a polymer modified asphalt and providing a compound of formula (IIa) or formula (II). The polymer modified asphalt is mixed with the compound of formula (IIa) or formula (IIb) under conditions effective to produce an improved asphalt, which is yet another aspect of the present invention.
