1、Designation: D 6440 05Standard Terminology Relating toHydrocarbon Resins1This standard is issued under the fixed designation D 6440; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses
2、 indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 The hydrocarbon resin industry continues to evolvefrom a source of replacement products for naturally-derivedmaterials to industrial materials that have no
3、 naturally-derivedcounterparts. Along with this changing character of the indus-try, various manufacturing participants have introduced termsthat have led to confusion among both manufacturers andconsumers. This terminology standard is intended to alleviatethat confusion and promote standard usage o

Terminology2.1 Definitions:C5aliphatic resin, na resin produced by the cationicpolymerization of a low-boiling aliphatic steam-crackerfraction.DISCUSSIONThe p
5、rincipal monomers are typically cis- and trans-piperylene (1,3pentadiene).C9aromatic resin, na resin produced by the cationicpolymerization of heavy aromatic steam-cracker or coal-tarfractions.DISCUSSIONThe C9designation is broad and may include styrene,indene, methylstyrenes, and methylindenes. Dep
6、ending on the sourceof the C9fraction, it may also include coumarone and dicyclopentadi-ene.cloud point, nthe temperature at which a defined liquidmixture, under controlled cooling, produces perceptible hazeor cloudiness due to the formation of fine particles of anincompatible material.dicyclopentad

8、lymer that is either mined, or madeprimarily from one or more of the following: certainsteam-cracked petroleum fractions, coal-tar fractions, ter-pene fractions, and streams rich in unsaturated monomersthat typically have five or more carbon atoms.DISCUSSIONTypical hydrocarbon resins are brittle sol
9、ids at roomtemperature, chemically similar semi-solid and liquid materials areincluded by association. This term also covers derivatives of hydrocar-bon resins.hydrogenated resin, na resin that has been subjected tosome degree of reaction with hydrogen to decrease the levelof residual unsaturation.n
10、atural resin, na resin of vegetable or animal origin.DISCUSSIONThis term includes rosins, wood extracts or papermanufacturing by-products, fossil resins, mined resin, secretion prod-ucts from insects, and their main derivatives. In the context ofhydrocarbon resins, this refers to mined bituminous re
11、sins.polyterpene resin, na resin produced by the polymerizationof terpene fractions or mixtures of terpenes obtained fromnaval stores, or paper pulp production, or citrus juiceproduction, or combinations thereof.DISCUSSIONTerpene fractions (turpentine oils) can be derived fromgum turpentine, wood tu
12、rpentine, or sulfate turpentine; citrus juiceproduction yields a d-limonene fraction as an extract of the peel.pure monomer resin, na resin produced by the polymeriza-tion of essentially pure compounds such as styrene, one ofthe methylstyrenes, or controlled mixtures of pure mono-mers.re-mass, vto f
13、orm, during storage, massive blocks fromparticulate forms, such as flakes, pastilles, or powder.DISCUSSIONRe-massing can occur with all resins but is influencedby storage temperature, and pressure, due to stacking; the lowersoftening point resins re-mass at lower temperatures. Particle sizedistribut
