The invention provides polymers comprising repeating units derived from at least one monomer comprising at least one functionalized or unfunctionalized acryloyl moiety and at least one lactam moiety; at least one monomer comprising at least one sulfonic acid moiety or a salt thereof; and at least one crosslinker. The invention further provides various compositions comprising the polymers. The invention furthermore provides applications of these compositions in various industrial arts, particularly in oilfield operations such as drilling and cementing.

A nanoparticle including at least one amphiphilic molecule and a polymer compound having a constitutional unit represented by Formula (1):

##STR00001## wherein, Ar.sup.1 and Ar.sup.2 represent a trivalent aromatic hydrocarbon ring group or a trivalent aromatic heterocyclic group; X and Y represent O, S, C(O), S(O), SO.sub.2, CR.sub.2, SiR.sub.2, NR, BR, PR, or P(O)(R); and R represents an alkyl group, aryl group, or the like; and n represents an integer of 1 or more.

Embodiments presented herein relate to various polymers. Some of the polymer embodiments are heparin binding polymers. Some embodiments of the heparin binding polymers can be employed to bind to heparin for methods such as separating, purifying, removing, and/or isolating heparin and heparin like molecules.

Sulfur copolymers having high sulfur content for use as raw materials in 3D printing. The sulfur copolymers are prepared by melting and copolymerizing one or more comonomers with cyclic selenium sulfide, elemental sulfur, elemental selenium, or a combination thereof. Optical substrates, such as films and lenses, are constructed from the sulfur copolymer via 3D printing and are substantially transparent in the visible and infrared spectrum. The optical substrates can have refractive indices of about 1.75-2.6 at a wavelength in a range of about 500 nm to about 8 m.
