HISTORY OF THE INSTITUTE

• CJSC Yerevan SRI Plastpolymer was founded in
  1958.
• The essential course of scientific activity has
  been synthesis of vinylacetate (VA) and polymers
  on its basis.
• Work in this field allowed to organize over 20
  large-capacity productions of VA and PVA
  plastics.
• The institute in the former USSR exercised
  scientific-technical control over more than 20
  large chemical complexes, as well as kept close
  contacts with over 35 scientific research
  enterprises.

Institute includes Scientific-Research and
Industry Departments

CURRENT ACTIVITIES OF THE INSTITUTE

• Scientific-Research Activities
• Synthesis of copolymers of VA with unsaturated
  carbonic acids
• Synthesis of poly (vinylalcohol) and its modified
  forms
• Synthesis of PVA, double and ternary copolymers
  on the basis of VA in the form of dispersions,
  suspensions and laquers
• Synthesis of high molecular weight PVA with low
  branching and narrow molecular weight
• Technological processes of obtaining vinyl
  esters and carriers and effective catalysts for
  them.

CURRENT ACTIVITIES OF THE INSTITUTE

• The Industry Department consists of the Pilot
  Plant and Industry Plant
• The Pilot Plant is unique because
• allows refinement of the technological
  parameters, i.e. is an interface between
  laboratory and industrial technologies
• represents the technological lines with
  processing volumes from 60 liter up to 200
  liter
• is useful for production of experimental batches
  of PVAD differ trademark, of PVAc and MPVAc
  differ trademark from 20 kg up to 100 kg
• The Industry Plant has a productive capacity for
  PVAD up to 600 t/year and for PVAc 80-100 t/year

PRESENTATION OF TECHNOLOGIES

• Synthesis of copolymers of VA with UCA homo-
  and copolymers (double and ternary) on the basis
  of VA modified poly (vinylalcohol) as well as
  high molecular weight PVA

Modified Poly(vinylalcohol) Using of MPVAc
instead of PVAc in aqueous glues for wood
allow to markedly enhance gluing ability
simultaneously to simplify their composition
New series of water-soluble and water- diluted
VA-acrylic acid copolymers as emulsions and as
solutions. The advantages over known PVAD is
simplified manufacturing These products can be
used for thickeners, new composites, glues, plant
protection means, etc
6
APPLICATION OF TECHNOLOGIES

• The polymer materials on VA basis have various
  applications owing to large mark assortment. The
  institute disposes KNOW-HOW over 10 marks of
  PVA dispersions, over 7 marks of polyvinyl
  alcohol , differing by molecular weight, content
  of residual acetate groups and natrium acetate
• Their use as glues and binding agents predominate
  in polygraphs, textile, furniture, varnish and
  paint industry, also used in such specific fields
  as medicine, every day chemistry, and food
  industry

7
APPLICATION OF TECHNOLOGIES

• New types of carriers on the basis of local
  mineral raw materials and high effective
  catalysts on their basis, can be used for
  processes of gas phase synthesis from olefines of
  vinyl and allyl monomers
• Copolymers on the basis of cloroprene used as
  the main component for obtaining rubbers and
  elastomers with increased stability to ?
  radiation.

COOPERATION WE ARE LOOKING FOR

• Two preferable forms of cooperation in the field
  of thorough investigations and scientific-technica
  l (ST) programs should refer
• 1. On non commercial basis
• 2. On commercial basis
• Transmission of ST knowledge and technologies on
  license principles.
• Conducting joint investigations.
• Implementation of contractual research.
• ST cooperation within the limits of joint
  enterprises, or temporary ST teams and
  laboratories.
