Important applications of polymers like PVAc, PP, BUNA-S
- 1. GEETANJALI COLLEGE OF ENGINEERING AND TECHNOLOGY UGC AUTONOMOUS ENGINEERING CHEMISTRY THEORY ABSTRACT Subject: Important applications of polyvinyl acetate, poly propylene, BUNA- S A polymer is any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, which are multiples of simpler chemical units called monomers. some of the important polymers used in our daily life are polyvinyl acetate, polypropylene, BUNA-S, etc. polyvinyl acetate (PVAc), a synthetic resin prepared by the polymerization of vinyl acetate. In its most important application, polyvinyl acetate serves as the film-forming ingredient in water-based (latex) paints; it also is used in adhesives. Polypropylene (PP) is a thermoplastic “addition polymer” made from the combination of propylene monomers. It is used in a variety of applications to include packaging for consumer products, plastic parts for various industries including the automotive industry, special devices like living hinges, and textiles. Buna-N is a commonly used elastomer. Buna-N is also known as Nitrile rubber, NBR or Perbunan. It is synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. Elastomer is natural or synthetic material which does not break when stretched and when released it return to its original length. GROUP NUMBER: 06 S.No Name Roll No. Signature 01.
