Emulsion polymers, or synthetic latex, have a variety of applications where they offer a superior alternative to their natural counterparts. Stepto Iii paper coatings styrene-butadiene copolymers have long dominated the market due to their low cost advantage. The preforms are shaped to a mold with compression, pressure, and vulcanization.

James, who noted that latex. Dried latex from the opium poppy is called opium , the source of several useful analgesic alkaloids such as codeine , thebaine , and morphine , the latter two of which can then further be used in the synthesis and manufacture of other typically stronger opioids for medicinal use, and of heroin for the illegal drug trade.

About half of people with spina bifida are also allergic to natural latex rubber, as well as people who have had multiple surgeries, and people who have had prolonged exposure to natural latex.

Description: Lewinsohn These toxins include ones that are also toxic to the plant and consist of a diverse range of chemicals that are either poisonous or " antinutritive ".
