• polymers, including those of ethylene, propylene, styrene, vinyl chloride, vinyl acetate and acrylics
• polyamides
• phenolic and epoxide resins and polyurethanes
• alkyd and polyester resins and polyethers
• silicones
• ion-exchangers based on polymers

• manufacture of synthetic rubber in primary forms:

• synthetic rubber
• factice
