Compositions containing 1,1-disubstituted alkene compounds for preparing polymers having enhanced glass transition temperatures
First Claim
1. 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°
