摘要： An alkyd polymer composition for fast-drying, low VOC applications is provided. The alkyd polymer incorporates a minimum required level of a cyclic ether- and hydroxyl-containing composition formed from a sugar alcohol during the alcoholysis step while synthesizing the alkyd polymer. The disclosure also relates to the cyclic ether- and hydroxyl-containing composition which must have a minimum required level of cyclic ether structure incorporated therein in order to produce a sufficiently fast-drying alkyd polymer. Methods of making the cyclic ether- and hydroxyl-containing composition and the alkyd polymer comprising, as polymerized units, the cyclic ether- and hydroxyl-containing composition and a poly acid and/or an anhydride compound, as well as an optional polyol, other than the sugar alcohol, are also provided. Also provided is a 13 C NMR method of characterizing the necessary minimum required level of cyclic ether ring structure in the cyclic ether- and hydroxyl-containing composition and the alkyd polymer formed therefrom.

摘要： An end and monomer functionalized poly(propylene fumarate) polymer and methods for preparing this polymer, comprising isomerized residue of a maleic anhydride monomer and a functionalized propylene oxide monomer according to the formula: where n is an integer from more than 1 to 100; R is the residue of an initiating alcohol having a propargyl, norbornene, ketone or benzyl functional group; and R′ is a second functional group selected from the group consisting of propargyl groups, 2-nitrophenyl groups, and combinations thereof are disclosed. The end and monomer functional groups allow for post-polymerization modification with bioactive materials using “click” chemistries and use of the polymer for a variety of applications in medical fields, including, for example, 3-D printed polymer scaffold.

摘要： Described herein polymer precursor compounds (aka polymer building blocks) of derived from biobased compounds, and specifically biobased mevalonolactone and its related derivatives. Through oxidation these biobased precursors can be reacted to yield building blocks for (unsaturated-) polyesters, polyester polyols and polyamides, as well as precursors for glycidyl esters and omega-alkenyl esters. Through reduction, these biobased precursors can be reacted to yield building blocks for (unsaturated-) polyesters, polyester polyols, polycarbonates, as well as precursors for glycidyl ethers and omega-alkenyl ethers. Through nucleophilic ring opening and/or amidation, these biobased precursors can be reacted to yield building blocks for polyester polyols, chain-extender for polyurethanes, or polyester-amides.
