    Abstract: Disclosed are compositions comprising polyester macromers containing in one or more chains the residue of one or more diols and one or more diesters wherein the residue of the one or more diols and the one or more diesters alternate along the chain and a portion of the diesters are 1,1-diester-1-alkenes, and optionally one or more dihydrocarbyl dicarboxylates, and at least one terminal end comprises the residue of one of the 1,1-diester-1 alkenes and wherein one or more terminal ends may comprise the residue of one or more diols. The chains may contain the residue of the one or more diols and one or more diesters comprising one or more diesters 1,1-diester-1 alkenes and optionally one or more dihydrocarbyl dicarboxylates randomly disposed along the chains. Disclosed are methods of preparing the polyester macromers and incorporating them in a variety of polyester containing compositions such as coatings and films.

    Abstract: Method to obtain methylene malonate and related monomers following a bis(hydroxymethyl) malonate pathway. A bis(hydroxymethyl) malonate intermediary is subsequently reacted (i.e., subjected to thermolysis) to provide a methylene malonate monomer species. A source of formaldehyde (e.g., formalin) is provided in the presence of a basic catalyst (e.g., calcium hydroxide), to which a malonate (e.g., diethyl malonate) is added under suitable reaction conditions to obtain the desired intermediary (e.g., dialkyl bis(hydroxymethyl) malonate). The intermediary is reacted (i.e., subjected to thermolysis) under suitable conditions in the presence of a suitable catalyst (e.g., a zeolite) to obtain a methylene malonate monomer. In an exemplary embodiment, the thermolysis reaction includes the addition of the bis(hydroxymethyl) malonate intermediary onto a heated catalyst. The reaction product is collected and purified. The disclosed methods may be performed in a continuous operation. Discrete steps may be performed by using modular units within a plant.
