Definition

1. Noun:
   • A synthetic thermoplastic material: A "polyvinyl resin" is a type of plastic polymer created through the chemical process of polymerization, using compounds that contain the vinyl group (a specific molecular structure of carbon and hydrogen) as the primary building blocks. These resins are known for being moldable when heated and solid when cooled.

Usage Examples

• Noun:
  • The toy is made from a durable polyvinyl resin.
  • Polyvinyl resin is commonly used in the production of pipes and fittings.

Advanced Usage

• Technical Context: In industrial and chemical contexts, "polyvinyl resin" often refers specifically to the base polymer before it is compounded with plasticizers, stabilizers, or pigments to become a finished plastic like PVC (polyvinyl chloride).
  • The manufacturer ordered a shipment of pure polyvinyl resin for their new production line.

Variants and Related Words

• Polyvinyl chloride (PVC) (n): A very common and specific type of polyvinyl resin, widely used in construction, healthcare, and consumer goods.
  • PVC pipes are made from a chlorinated polyvinyl resin.
• Vinyl polymer (n): A broader category of polymers derived from vinyl monomers, which includes polyvinyl resin.
• Thermoplastic (n): A general class of polymers, including polyvinyl resins, that become pliable or moldable above a specific temperature.

Synonyms

• Vinyl polymer
• Synthetic resin (in a broader sense, as not all synthetic resins are vinyl-based)

Related Phrases

• Polyvinyl acetate (PVA): A specific type of polyvinyl resin used in adhesives and paints.
• Polyvinyl alcohol (PVOH): A water-soluble polyvinyl resin.

Noun

1. a thermoplastic derived by polymerization from compounds containing the vinyl group
