Korean Kongkae Taeho Kongbo KR 2002055865 A 10 Jul 2002, No pp. given (Korean). (Korea, Republic Of). CODEN: KRXXA7. CLASS: ICM: C08L023-12. APPLICATION: KR 2000-85108 29 Dec 2000. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Provided is a polypropylene resin compn. which has high transparent and low effluvium, and which essentially does not shows a bleed phenomenon of additives. The polypropylene resin compn. comprises 100 parts by wt. of polypropylene resin and 0.01-2 parts by wt. of 1,3: 2, 4-di(dialkylbenzylidene)sorbitol nucleating agent having a structure of specified formula 1(wherein each of R1 and R2 represents an alkyl group having C1-C6). The polypropylene resin is at least one selected from a group consisting of isotactic polypropylene, copolymer of propylene and ethylene, and copolymer of propylene and alpha-olefin. The 1,3:2,4-di(dialkylbenzylidene)sorbitol nucleating agent is 1,3:2,4-di(3,4-dimethylbenzylidene)sorbitol. .

DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 36 Modification of isotactic polypropylene (iPP) with two nucleation agents, namely 1,3:2,4-bis(3,4-dimethylbenzylidene)sorbitol (DMDBS) (a-nucleator) and N,N'-dicyclohexyl-2,6-naphthalenedicarboxamide (NJ) (b-nucleator), leads to significant changes of the structure, morphol. and other properties. Both nucleating agents cause an increase in the crystn. temp. The efficiency detd. in a self-nucleation test is 73. 135861-56-2 and 25085-53-4 which are cas registry numbers of chemicals are mentioned.4% for DMDBS and 55.9% for NJ. The modification with NJ induces the creation of the hexagonal b-form of iPP. The addn. of DMDBS lowers the haze of iPP while the presence of NJ increases the haze. .
