摘要:
The disclosure relates to compositions containing 1,1-disubstituted alkene compounds capable of preparing polymers having glass transition temperatures above room temperature. The present teaching also relates to polymers prepared 1,1-disubstituted alkene compounds which exhibit glass transition temperatures of 60° C. The disclosure also relate to methods for enhancing the glass transition temperatures of polymers prepared from 1,1-disubstituted alkene compounds.

摘要:
The present teachings disclose contacting an amine salt catalyst with a dicarbonyl compound having an alkylene group between the carbonyl group; adding formaldehyde, paraformaldehyde, or formalin in an amount of about 2:1 to about 3:1 moles of formaldehyde to moles of the dicarbonyl compound to form a mixture; and refluxing the mixture. The process forms a carbonyl-substituted alkene. The process may be performed in the absence of a solvent. The process may form methylene malonates, methylene dimalonates, methylene keto malonamides, methylene diketones, methylene keto esters, and the like.

The disclosure relates to compositions containing 1,1-di-carbonyl-substituted alkene compounds capable of preparing polymers having glass transition temperatures above room temperature. The present teaching also relates to polymers prepared 1,1-di-carbonyl-substituted alkene compounds which exhibit glass transition temperatures of 60° C. The disclosure also relate to methods for enhancing the glass transition temperatures of polymers prepared from 1,1-di-carbonyl-substituted alkene compounds.
摘要:
Functionalized compounds including residues of one or more 1,1-disubstituted alkene compounds. Preferably the functionalized compound includes the residue of two or more 1,1-disubstituted alkene compounds, which are spaced apart. The functionalized compound may be produced by a transesterification reaction. The functionalized compounds may be employed in a polymerizable composition and may be used to prepare new polymers, (for example by reacting the alkene group).
摘要:
Disclosed are graft copolymers, compositions including graft copolymers, intermediate materials, and related methods, where the graft copolymer includes a first polymer component including a 1,1-disubstituted-1-alkene compound (preferably a methylene malonate compound) and is grafted to a second component. The resulting graft copolymer may be hydrophilic or water soluble. The second component preferably is a hydrophilic component.
