3 ways Chinaâs economic slowdown will affect your finances. The focus on Chinese equity markets distracts us from the more important underlying development: Chinaâs economy is slowing, and it will have global implications. Photo by Luo Yunfei/CNSPHOTO/ChinaFotoPress via Getty Images.
A polyolefin is any of a class of polymers produced from a simple olefin (also called an alkene with the general formula C n H 2n) as a monomer.For example, polyethylene is the polyolefin produced by polymerizing the olefin ethylene. Polypropylene is another common polyolefin which is made from the olefin propylene.olyolefin properties range from liquidlike to rigid solids, and are primarily determined by their molecular weight and degree of crystallinity. Polyolefin degrees of crystallinity range from 0% (liquidlike) to 60% or higher (rigid plastics).
Polystyrene (PS) /ËpÉliËstaÉªriËn/ is a synthetic aromatic polymer made from the monomer styrene.Polystyrene can be solid or foamed. General purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight.s a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 Â°C, its glass transition temperature.
