Acetone

Acetone is a good solvent for most plastics and synthetic fibers including those used in laboratory bottles made of polystyrene, polycarbonate and some types of polypropylene. It is ideal for thinning fiberglass resin, cleaning fiberglass tools and dissolving two-part epoxies and superglue before hardening. It is used as a volatile component of some paints and varnishes. As a heavy-duty degreaser, it is useful in the preparation of metal prior to painting, it also thins polyester resins, vinyl and adhesives.

Synthetic rubber

Synthetic rubber is any type of artificial elastomer, serves as a substitute for natural rubber in many cases, especially when improved material properties are required. Synthetic rubber is used a great deal in printing textile. In this case it is called rubber paste.
In most cases titanium dioxide is used with copolymerization and volatile matter in producing such synthetic rubber for textile use. Moreover this kind of preparation can be considered to be the pigment preparation based on titanium dioxide.

Synthetic Rubber
Synthetic rubber is actually derived from natural rubber. With a methods and specific process synthetic rubber can be produced, everything is so complicated that it's hard to explain. Science and technology needed for it all.

Solvent For Synthetic Rubber

The effect of solvent characteristics on the vicosity of several synthetic rubber-hydrocarbon solutions was determined. Normal and isoparaffins yeilded lower vicosity solutions than Naphthenese and aromatics at 10 weight % and 8 grams of rubbers per 100cc of solvent, concentrations of interest to rubber cement adhesive manufactures. Solubility varied markedly with elastomer and solvent. Butadiene acriconitrile capolymer and ethylene propylene terpolymer were the least solube; cis-polyisopropene, butyl rubber and ethylene propylene capolymer were solube in all thinner. No general correlation was found ond solvent volume basis between solution vicosity and solvent vicosity or between relative vicosity and hydrocarbon type.

Polybutadiene

Polybutadiene (BR) is the second largest volume synthetic rubber produced, next to styrene- butadiene rubber (SBR). Consumption was about 1,953,000 metric tons worldwide in 1999. The major use of BR is in tires with over 70% of the polymer produced going into treads and sidewalls. Cured BR imparts excellent abrasion resistance (good tread wear), and low rolling resistance (good fuel economy) due to its low glass transition temperature (Tg). The low Tg , typically <–90C, is a result of the low “vinyl” content of BR, which will be discussed below. However, low Tg also leads to poor wet traction properties, so BR is usually blended with other elastomers like natural rubber or SBR for tread compounds. BR also has a major application as an impact modifier for polystyrene and acrylonitrile-butadiene-styrene resin (ABS) with about 25% of the total volume going into these applications. Typically about 7% BR is added to the polymerization process to make these rubber-toughened resins (see picture below). Also, about 20,000 metric tons worldwide of “high cis” polybutadiene is used each year in golf ball cores due to its outstanding resiliency. This application is growing since the golf ball industry seems to be moving away from the traditional wound ball technology to the two-piece, solid core construction.
