    摘要: A polymer composition adapted for use in injection stretch blow molding may include a metallocene random propylene-based copolymer in the absence of a clarifier. The metallocene random propylene-based copolymer may exhibit a melting point of from 105° C. to less than 175° C., a recrystallization temperature ranging from 85° C. to 100° C. as measured by DSC, a microtacticity ranging from 89% to 99%, a molecular weight (Mw) ranging from 170,000 to 210,000, and a melt flow rate of from about 1 dg/min. to about 40 dg/min. A method of forming an injection stretch blow molded (ISBM) article may include providing the metallocene random propylene-based copolymer, injection molding the metallocene random propylene-based copolymer in the absence of a clarifier into a preform, and stretch-blowing the preform into an article.

    摘要: Disclosed is a polystyrene based polymer/layered compound nanocomposite for injection blow molding or injection stretch blow molding of articles. The nanocomposite can reduce shrinkage and warpage to the preform during the reheating process compared to neat polystyrene. The incorporation of layered compounds can increase the processability of PS preforms, help improve heating efficiency, and improve bottle mechanical properties. The layered compound can be treated with chemicals or compounds having an affinity with the styrene monomer or polystyrene, thus producing a treated layered compound having an affinity with the styrene monomer or polystyrene. The monomer and the layered compound can be combined prior to polymerization. The polymer and layered compound can be combined by solution mixing in a solvent. The layered compound can also be incorporated into the mixture by compounding a polymer product with the layered compound, or the combination of any of the above three approaches
