摘要:
A polythioether includes a structure having the formula I--R.sup.1 --�--S--(CH.sub.2).sub.2 --O--�--R.sup.2 --O--!.sub.m --(CH.sub.2).sub.2 --S--R.sup.1 --!.sub.n --whereinR.sup.1 denotes a divalent C.sub.2-6 n-alkyl, C.sub.3-6 branched alkyl, C.sub.6-8 cycloalkyl or C.sub.6-10 alkylcycloalkyl group, --�(--CH.sub.2 --).sub.p --X--!.sub.q --(--CH.sub.2 --).sub.r --, or --�(--CH.sub.2 --).sub.p --X--!.sub.q --(--CH.sub.2 --).sub.r -- in which at least one --CH.sub.2 -- unit is substituted with a methyl group,R.sup.2 denotes methylene, a divalent C.sub.2-6 n-alkyl, C.sub.2-6 branched alkyl, C.sub.6-8 cycloalkyl or C.sub.6-10 alkylcycloalkyl group, --�(--CH.sub.2 --).sub.p --X--!.sub.q --(--CH.sub.2 --).sub.r --, or --�(--CH.sub.2 --).sub.p --X--!.sub.q --(--CH.sub.2 --).sub.r -- in which at least one --CH.sub.2 -- unit is substituted with a methyl group,X denotes one selected from the group consisting of O, S and --NR.sup.6,R.sup.6 denotes H or methyl,m is a rational number from 0 to 10,n is an integer from 1 to 60,p is an integer from 2 to 6,q is an integer from 0 to 5, andr is an integer from 2 to 10.The polythioether is a liquid at room temperature and pressure.
