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.

Acrylated and acylated or acetalized polyol as a biobased substitute for hard, rigid thermoplastic and thermoset materials

Provided herein are an emulsified asphalt product and an emulsified coating product. Both emulsified products contain one or more rejuvenators of formula (I) or formula (X). The emulsified asphalt product is useful for improving the performance of aged or brittle resinous binders in paving applications while the emulsified coating product is similarly useful in roofing applications. Also provided herein is a treated bituminous pavement where the performance grade varies with depth.
