strong synthetic resin {alkyd resin}.
colorless nitrocellulose and camphor {celluloid}.
C6H10O5 [6, 10, and 5 are subscripts] plus acetic acid {cellulose acetate}.
C6H10O5 [6, 10, and 5 are subscripts] plus nitric acid {cellulose nitrate}.
Two different plastics {copolymer} have bonds between them.
Polyesters {Dacron} do not wrinkle.
Two different plastics {diblock copolymer} have bonds between them but are two separate phases.
Elastomer plastics {electroactive polymer}| (EPA) can move by applying electric or magnetic fields.
ionic
Ionic polymer gels, ionomeric polymer-metal complexes, conductive polymers, and carbon nanotubes use low voltage and keep expanding or contracting at any voltage.
electronic
Ferroelectric polymers {perovskite}, electrets, dielectric silicone or acrylic elastomers, and electrostatic graft elastomers use high voltage.
insulator
Insulators contract in electric-field direction and so expand perpendicular to field {Maxwell stress}. Ferroelectric random-access memory (FRAM) uses dipoles as bits. Dipoles can be left or right spirals.
laminated plastic {Formica}.
Plastic sheets {linoleum} can be floor coverings.
Semiconductor polymers {oligothiophene} can have molybdenum or tungsten doping, which allows phosphorescence and fluorescence.
lightweight acrylic polymer {Orlon}.
ethylene polymer resin {polyethylene}.
rayon {rattail}.
thermoplastic resin {saran}.
Shrink-wrap {shape-memory polymer} (SMP) can hold shape. Other compounds, such as SMP polyurethane, change back to original shape at temperature. Cross-links determine shape. SMPs can be thermosetting or thermoplastic. Linear block copolymers have cross-link sections and shape-memory change segments.
Clear, flexible, thermally stable, inert, and water-repellent material {silicone} is R2SiO [2 is subscript] units, where R is any organic group. Elastic sealants {silicone rubber} can be for interior and exterior movable joints.
Plastics can be fibers {synthetic fiber}|.
Acrylonitrile and starch digested by lye [1884] make nitrocellulose {rayon fiber}. Rayon is absorbent, is soft, does not pill, and is not electric.
Synthetic fiber {polyester fiber} can be strong but electric.
Synthetic fiber {acetate fiber} can be lustrous and soft, such as Dacron.
Synthetic fiber {triacetate fiber} can be like acetate.
Acrylic synthetic fiber {acrylic fiber} can be wool-like and be for imitation fur. Synthetic fiber {modacrylic fiber} can be fur-like and flame resistant.
Nylon is strong. Synthetic fibers {Kevlar} can be strong and bulletproof.
Plastics {thermoplastic}| can melt at 120 C and easily mold. Vinyl, food wrap, furniture covers, and screens are thermoplastics.
Two chemicals can react when heated and then cool and stiffen in molds {thermosetting plastic}|. Thermosetting plastics melt only at high temperatures.
types
Thermosetting plastics include acrylonitrile, polyethylene, polypropylene, polyvinyl chloride, polyvinyl alcohol, PET, and Teflon. Strong thermosetting plastics are lexan {polycarbonate} and Zytel-ST nylon. Thermosetting plastics can be insulators {phenolic} {Bakelite} [1909], dishes {melamine}, and cups {polystyrene} {Styrofoam}. Clear products {acrylic plastic} are Plexiglas {polymethyl-methacrylate} (PMMA), Orlon, and Acrilan. Polyamide {nylon} can be in stockings and toothbrushes. Dynel is part vinyl and acrylic. Thermosetting plastic can be from urea {urea derivative}.
vinyl polymer {vinyl}.
