谁帮我讲讲“接枝”“嵌段”等专业术语
|
|||
| 热固性树脂能用这些词语么？比如我想改性酚醛树脂，我想把柔性链引入到酚醛结构中，如何是算接枝？如何算是嵌段？ |

看看英文聚合物词典里怎么解释这个词的吧。 Block n. A portion of a polymer molecule comprising many mer units that has at least one constitutional or configurational feature not present in the adjacent portions. Block copolymers n. (1) A copolymer with chains composed of shorter homopolymeric chains that are linked together. These ‘‘blocks’’ can alternate regularly or randomly. Such copolymers usually have some higher properties than either of the homopolymers or their physical blends. Graft copolymer n. A copolymer having branches of varying length made up of different monomer units on a common ‘‘backbone’’ chain. Odian GC (2004) Principles of polymerization. John Wiley and Sons Inc., New York. They have distinct blocks of polymer segments such as, AAAABBBBAAAABBBAAA sequencing of A and B monomers. When blocks are of different monomer species, the term block copolymer is used. (2) An essentially linear copolymer in which there are repeated segments of different chemical structure. Odian GC (2004) Principles of polymerization. John Wiley and Sons Inc., New York. Graft copolymer n. A copolymer having branches of varying length made up of different monomer units on a common ‘‘backbone’’ chain. Odian GC (2004) Principles of polymerization. John Wiley and Sons Inc., New York. Graft polymer or copolymer n. A high polymer, the molecules of which consist of two or more polymeric parts of different composition, chemically united. Such a graft copolymer may be produced, for example, by polymerization of a given kind of monomer with subsequent polymerization of another kind ofmonomer onto the product of the first polymerization. The union of two different polymers by chemical reaction between their molecular end groups or by reaction producing cross‐links between the different molecules would also produce a graft copolymer.
