miscible polymer blends (homogeneous polymer blends): Polymer blend that is a single-phase structure. In this case, one glass transition temperature will be observed. The use of the term polymer alloy for a polymer blend is discouraged, as the former term includes multiphase copolymers but excludes incompatible polymer blends. [3]
As wood glue, PVAc is known as "white glue" and the yellow as "carpenter's glue". As paper adhesive during paper packaging conversion. In bookbinding and book arts, due to its flexible strong bond and non-acidic nature (unlike many other polymers).
block copolymer: A copolymer that is a block polymer. In the constituent macromolecules of a block copolymer , adjacent blocks are constitutionally different, i.e. adjacent blocks comprise constitutional unit derived from different species of monomer or from the same species of monomer but with a different composition or sequence distribution ...
Polyurethane synthesis, wherein the urethane groups −NH−(C=O)−O− link the molecular units A kitchen sponge made of polyurethane foam . Polyurethane (/ ˌ p ɒ l i ˈ jʊər ə ˌ θ eɪ n,-j ʊəˈr ɛ θ eɪ n /; [1] often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links.
The PPE blends are characterized by hot water resistance with low water absorption, high impact strength, halogen-free fire protection and low density. This plastic is processed by injection molding or extrusion; depending on the type, the processing temperature is 260–300 °C.
bone glue, and fish glue including isinglass. Animal connective tissue. and bones hides are acid-treated, neutralized, and repeatedly soaked; the soaking-water is dried into chips hydrolyzed collagen: Until it cools Thermoplastic. Somewhat brittle when set Water-soluble Cabinetmaking, bookbinding, lutherie, glue-size: Keratin glues Hoof glue ...
