The disclosure relates to compositions comprising a polysaccharide derivative, wherein the polysaccharide derivative comprises a polysaccharide substituted with a) at least one hydrophobic group, and b) at least one hydrophilic group, wherein the polysaccharide is poly alpha-1,3-glucan, poly alpha-1,6-glucan, or poly alpha-1,3-1,6-glucan.

Amphiphilic polysaccharide derivatives and compositions comprising same

The invention pertains to a printing form and a process for preparing a polymeric printing form from a curable composition that includes a multifunctional urethane in a specified reactive group equivalent weight range, and an initiator. The process includes coating the curable composition onto a supporting substrate, such as a print cylinder, to form a layer, curing the layer with heat or by exposure to actinic radiation, and engraving the resulting cured layer to form at least one printing cell in the cured layer. The process prepares novel polymeric printing forms, particularly novel polymeric gravure printing forms, having a cured polymer-based composition layer that is engravable, resistant to solvent inks, and capable of printing gravure-quality images. The present invention shortens the time to prepare gravure printing cylinders and removes the need for and disposal of toxic heavy metals such as copper and chrome associated with conventional gravure print cylinder preparation.

A method is provided for the thermal decarboxylation of a phenolic substrate in the presence of a non-amine basic catalyst to produce a vinyl monomer. The product of the decarboxylation reaction may additionally be acetylated in the presence of an acetylating agent in the same reaction vessel.

Method for preparing hydroxystyrenes and acetylated derivatives thereof

It was found that glycidyloxystyrenes, including glycidyloxystyrene and substituted glycidyloxystyrene, can be synthesized from hydroxycinnamic acid or substituted hydroxycinnamic acids in a one-pot, two-step process. The substrate can be thermally decarboxylated and then without purification, reacted in the presence of a halomethyl-oxirane and a base. The resulting product can be polymerized or coppolymerized to a fully substituted product.

Method for preparing glycidyloxystyrene monomers and polymers thereof

Tyrosine was converted to p-hydroxystyrene in a two-step reaction without purification of individual intermediates. Conditions were determined for bromination of tyrosine in which reactive intermediates were formed. The mixture of these intermediates was used directly in a second step reaction to produce p-hydroxystyrene. The p-hydroxystyrene was further acetylated to produce p-acetoxystyrene in the second step reaction vessel.

Processes for conversion of tyrosine to p-hydroxystyrene and p-acetoxystyrene
