Abstract
Some embodiments of the present disclosure relate to a method comprising obtaining a mixture comprising at least one vinyl polymer, at least one organic acid, and at least one hydronium ion donor. In some embodiments, the method comprises reacting an —OH group of the B polymer chain segment with the at least one organic acid in the presence of the at least one hydronium ion donor, so as to form at least one polyvinyl ester. Some embodiments of the present disclosure relate to a roofing material comprising at least one reinforcement material and at least one polyvinyl ester.
Claims20
A roofing material comprising:
- a substrate,
- wherein the substrate comprises at least one of a fiberglass mat, a polyester mat, or any combination thereof;
- at least one reinforcement material;
- and
- at least one polyvinyl ester,
- wherein the at least one polyvinyl ester is interspersed with the at least one reinforcement material,
- wherein the at least one polyvinyl ester comprises the following polymer chain segments:
- wherein R is an ester group, and
- wherein the polymer chain segment B′ is different from the polymer chain segment C;
- and
- wherein the roofing material exhibits at least one of the following:
- an elongation of 50% to 500% based on ASTM D828,
- a tensile strength of 35 lbf to 130 lbf, based on ASTM D828,
- a tear of 500 gf to 2500 gf, based on ASTM D1922, or
- any combination thereof.
A roofing system comprising:
- a roof substrate;
- and
- a roofing material on the roof substrate,
- wherein the roofing material comprises:
- a substrate,
- wherein the substrate comprises at least one of a fiberglass mat, a polyester mat, or any combination thereof,
- at least one reinforcement material;
- and
- at least one polyvinyl ester,
- wherein the at least one polyvinyl ester is interspersed with the at least one reinforcement material,
- wherein the at least one polyvinyl ester comprises the following polymer chain segments:
- wherein R is an ester group, and
- wherein the polymer chain segment B′ is different from the polymer chain segment C;
- and
- wherein the roofing material exhibits at least one of the following:
- an elongation of 50% to 500% based on ASTM D828,
- a tensile strength of 35 lbf to 130 lbf, based on ASTM D828,
- a tear of 500 gf to 2500 gf, based on ASTM D1922, or
- any combination thereof.
A method comprising:
- obtaining a substrate,
- wherein the substrate comprises at least one of a fiberglass mat, a polyester mat, or any combination thereof;
- obtaining a mixture,
- wherein the mixture comprises:
- at least one vinyl polymer,
- wherein the at least one vinyl polymer comprises the following polymer chain segments:
- at least one organic acid, and
- at least one hydronium ion donor;
- and
- reacting the —OH group of the B polymer chain segment with the at least one organic acid in the presence of the at least one hydronium ion donor, so as to form at least one polyvinyl ester,
- wherein the at least one polyvinyl ester comprises the following polymer chain segments:
- wherein R is an ester group, and
- wherein the polymer chain segment B′ is different from the polymer chain segment C;
- and
- applying the at least one polyvinyl ester onto the substrate, so as to form a roofing material, wherein the at least one polyvinyl ester is interspersed with at least one reinforcement material.
