发明名称 Renewable polymer and method of making
摘要 A polymer, optionally made from renewable sources, comprising a specific chemical structure that is a result of the polymerization of α-hydroxycarbonyl compounds (alpha-hydroxycarbonyl compounds), particularly α-hydroxyaldehydes (alpha-hydroxyaldehydes) and α-hydroxyketones (alpha-hydroxyketones), or glycolaldehyde. A method of polymerization, the method comprising the step of reacting trimethylsilyl trifluoromethanesulfonate with the cyclic dimer of one or more α-hydroxycarbonyl compounds. A method of making said polymer, the method comprising dehydrating a cyclic dimer of one or more α-hydroxycarbonyl compounds. An end-capped polymer made from one or more α-hydroxycarbonyl compounds and terminal end-cap groups.

主权项 1. A polymer comprising the chemical formula: wherein: “n” is an integer number from 4 to 10,000,000, and “m” is an integer number from zero to 10,000,000; and R1, R2, R3, R4, R5, R6, R7, R8, R10, R12, R13, and R14, are independently from each other selected from the group consisting of hydrogen (—H), deuterium (-D), a halogen atom (—F, —Cl, —Br, —I), a hydroxyl group (—OH), an amino group (—NH2), an alkylamino group (—NHR9), a (bisalkylamino) group [—N(R9)2], an alkyl group, an alkenyl group, an alkynyl group, an alkoxy group, an alkoxyalkyl group, an alkoxyalkenyl group, an alkoxyalkynyl group, an haloalkyl group, an haloalkenyl group, an haloalkynyl group, an haloalkoxy group, an aryl group, an alkoxyaryl group, an haloaryl group, an alkylaryl group, an acyl group, an alkyl carbonate group, a thiol group (—SH), alkylthio (—SR9), a nitro group (—NO2), a cyano group (—C≡N), a isocyanate group (—N═C═O), a azide group (—N3), a cyanate group (—O═C═N), a nitroso group (—NO), a phosphine group [—P(R9)2], a phosphate group [—OP(O)(OR9)2], a phosphonate group [—P(O)(OR9)2], a sulfate group (—O—SO3R9), a sulfonate group (—SO3R9), a thiocyanate group (—S═C═N), a iso thiocyanate group (—N═C═S), a —COR9 group, a —COOR9 group, a —CON(R9)2 group, a —CSR9 group, a —CS—OR9 group, a —N(R9)2 group, a —CO—O—CO—R9, a —CO—NR9—CO—R9, a —N═C(R9)2, and a —CR9═NR9; and wherein, each R9 is independently from each other selected from the group consisting of a hydrogen, an alkyl, an aryl, an alkenyl and an alkynyl group; and R9 may be optionally substituted with one or more of the group consisting of halogen, hydroxy group, nitro group, cyano group, isocyano group, oxo group, thioxo group, azide group, cyanate group, isocyanate group, nitroso group, phosphine group, phosphate group, thiocyano group, and thiocyanate group.
