Abstract
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.
Claims20
A composition comprising about 10 weight percent or greater of one or more first 1,1-disubstituted alkene compounds wherein each carbonyl group independently has a hydrocarbyl group bonded to the carbonyl groups by a direct bond, an oxygen atom, a nitrogen atom or a sulfur atom wherein one or more of the hydrocarbyl groups comprise an aryl group, aralkyl group, alkaryl group with the aryl group bonded to the 1 or 2 carbon atom, a cycloalkyl group, an alkyl group with a cycloalkyl group on the 1 or 2 carbon atom, or a branched alkyl group wherein the 1 carbon atom is a tertiary or the 1 and 2 carbon atoms are secondary;
- and about 10 weight percent or greater of one or more second 1,1-disubstituted alkene compounds wherein each carbonyl group independently has a hydrocarbyl group bonded to the carbonyl groups by a direct bond or a heteroatom, and the hydrocarbyl groups are selected such that homopolymers prepared from the second 1,1-disubstituted alkenes exhibit glass transition temperatures of less than 60° C., wherein the first 1,1-disubstituted alkene compounds are different from the second 1,1-disubstituted alkene compounds, and wherein a polymer prepared from the composition exhibits a glass transition temperature of greater than 35° C.
A composition comprising a copolymer prepared from about 10 weight percent or greater of one or more first 1,1-disubstituted alkene compounds wherein each carbonyl group independently has a hydrocarbyl group bonded to the carbonyl groups by a direct bond, an oxygen atom, nitrogen atom or a sulfur atom wherein one or more of the hydrocarbyl groups comprising an aryl group, aralkyl group, alkaryl group with the aryl group bonded to the 1 or 2 carbon atom, a cycloalkyl group, an alkyl group with a cycloalkyl group on the 1 or 2 carbon atom, or a branched alkyl group wherein the 1 carbon atom is a tertiary or the 1 and 2 carbon atoms are secondary;
- and about 10 weight percent or greater of one or more second 1,1-disubstituted alkene compounds wherein each carbonyl group independently has a hydrocarbyl group bonded to the carbonyl groups by a direct bond, an oxygen atom, a nitrogen atom or a sulfur atom and the hydrocarbyl groups are selected such that homopolymers prepared from the second 1,1-disubstituted alkenes exhibit glass transition temperatures of 60° C. or less, wherein the first 1,1-disubstituted alkene compounds are different from the second 1,1-disubstituted alkene compounds, and wherein the copolymer has a glass transition temperature of greater than 35° C.
A composition comprising one or more first 1,1-disubstituted alkene compounds wherein each carbonyl group independently has a hydrocarbyl group bonded to the carbonyl groups by a direct bond, a heteroatom wherein one or more of the hydrocarbyl groups comprise a menthyl, fenchyl, isobornyl, furfuryl, phenethyl, 2-phenyl propyl or adamantyl.
