    摘要： Novel elastomeric compositions that contain at least one thermoplastic elastomer and at least one phase change solvent. Above the phase change temperature, the phase change solvent solubilizes or intimately mixes with the thermoplastic elastomers. Below the phase change temperature, the phase change solvent solidifies or crystallizes within the thermoplastic matrix. The phase change behavior of these materials produce elastomeric compositions that exhibit lowered viscosity and lowered processing temperature without substantially compromising the mechanical properties. The present invention also relates a method of lowering the viscosity and improving the processability of a thermoplastic elastomer using the phase change solvent.

    摘要： The present invention relates to compositions for controlling plant and flower moisture transpiration and thereby extending the period of time in which cut flowers can be displayed before senescence produces a flower which has exceeded its aesthetic value. The compositions of the present invention comprise: a) from about 0.1% to about 20% by weight, of a homopolymer or copolymer comprising monomers having the formula: wherein each R1 is independently hydrogen, C1-C12 alkyl, C1-C12 alkoxy, phenyl, substituted phenyl, benzyl, substituted benzyl, carbocyclic, heterocyclic, and mixtures thereof; R2 is hydrogen, halogen, C1-C12 alkyl, C1-C12 alkoxy, phenyl, substituted phenyl, benzyl, substituted benzyl, carbocyclic, heterocyclic, and mixtures thereof; X is hydrogen, hydroxyl, halogen, —(CH2)mCH2OH, —(CH2)mCOR, —(CH2)mCH2OCOR′, wherein R is —OR′, —N(R′)2, —(CH2)nN(R″)2, and mixtures thereof; each R′ is independently hydrogen, C1-C8 alkyl, C2-C8 hydroxyalkyl, —(CH2)nN(R″)2, and mixtures thereof; wherein R″ is independently hydrogen, C1-C4 alkyl, and mixtures thereof; the index m is from 0 to 6, the index n is from 2 to 6; b) from about 0.01% to about 5% by weight, of a surfactant; and c) the balance carriers and adjunct ingredients.
