9. Examples of Polymer Names (continued)

Example 61

(benzene is senior to acyclic carbon chain; the path from N to N through the ring can go in either direction because of the absence of a specific locant for the methyl group; Rules 1, 11)

Example 62

(path between the two oxygens through the acyclic carbon chain is shorter, since for the benzene ring with unknown positions of its attachment to other atoms the longest possible path of four carbon atoms is being considered; Rule 15)

Example 63

(heterocyclic ring system is senior to heteroatoms; Rules 1, 12)

Example 64

(pyridine is senior to pyrrole; shorter path; Rules 2d, 12)

Example 65

(O is senior to S; shorter path; Rules 4, 11)

Example 66

(O is senior to N; shortest path between O and N; Rules 4)

Example 67

(shorter path between two identical senior heterocycles; shorter path from heterocycle to carbocycle; Rules 1, 11, 12, 15)

Example 68

poly(oxymethyleneoxymethyleneiminoethylenesulfanediylmethyleneiminoethylene) or poly(1,3-dioxa-8-thia-5,10-diazadodecane-1,12-diyl)
(O is senior to S; shorter path from O to O to N; Rules 4, 15)

Example 69

poly(oxymethyleneoxymethyleneoxymethyleneimino-1,3-phenylenemethyleneiminomethylene) or poly(1,3,5-trioxa-7-azaheptane-1,7-diyl-1,3-phenylene-2-azapropane-1,3-diyl)
(O is senior; the shorter path through all oxygens to the ring has been taken; Rules 4, 11, 16)

Example 70

(heterocycle is senior; shorter path from pyridine to benzene; Rules 1, 11, 12)

Example 71

(shortest path between the heteroatoms; Rule 16)

Example 72

(O is senior to N; Rule 4)

Example 73

(N is senior; shorter path between N; Rules 1, 15)

Example 74

(O is senior to N; the direction of bonding in unsymmetrical nitrilo subunits, =N- or -N=, is indicated by the endings of the names of the adjacent subunits in the CRU; Rule 4)

Example 75

(O is senior to S; shorter path; Rule 4, 11)

Example 76

(either path through both N to ring; Rule 15)

Example 77

(O is senior to benzene; shorter path between them; Rules 1, 1515)

Example 78

(-N= is most senior; Rule 7a)

Example 79

(cyclohexane is most senior; the path to the next cyclohexane goes through a senior acyclic carbon atom -CH=; Rule 10a)
