22、erminology D1600,unless otherwise specified.3.2 Definitions of Terms Specific to This Standard:3.2.1 polypropylene random copolymer (PP-R) or polypropylene random copolymer with modified crystallinity and temperatureresistance (PP-RCT), na propylene plastic containing not more than 50% of another ol
23、efinic monomer (or monomers), havingno functional group other than the olefinic group, and copolymerized with the propylene.3.2.1.1 DiscussionPolypropylene materials are described in detail in ISO 15874. The performance of PP-R and PP-RCT is distinguished by theminimum reference curves in ISO15874.
24、Historically, PP-RCT has referred to a polypropylene random copolymer with modifiedcrystallinity that delivers performance characteristics referenced in ISO15874. However, recent developments make it possible toattain the PP-RCT performance requirements other than through modification of crystallini
25、ty.3.2.1.2 DiscussionThis term is also used for finished compound which comprises the PP-R or PP-RCT resin and additives such as colorants, UVinhibitors, and stabilizers. Polypropylene random copolymers containing more than one additional monomer are often referred toas “terpolymers.”3.2.2 plastic-t
