Abstract: A microbiocide-containing concentrate for use in thermoplastic polymers as well as in plastisols, is disclosed. The concentrate is primarily solid at ambient conditions and comprises from 1-30 wt% of a microbiocide, a polymer plasticizer and up to 20 wt% of a thermoplastic resin. These concentrates are primarily useful as masterbatch compositions used for incorporation into polymers in order to protect said polymers from fungal or bacterial attack. Along these lines, the present document also discloses processes for incorporating these materials into a polymer or plastisol, and polymers or plastisols made by these processes.

Abstract: In accordance with the present invention, there is provided a composition comprising the reaction product of particular (1).alpha.,.beta.-unsaturated dicarboxylic acid esters and (2) olefinically unsaturated compounds, wherein the resulting composition comprises a substantial amount of an intermediate molecular weight reaction product which is neither the well-known lower molecular weight alkenyl or alkyl succinic reaction product, nor the well-known polymerization reaction product, of (1) and (2). The compositions of the present invention are particularly suitable for use as lubricants and lubricant additives. In accordance with the present invention, there is also provided a process for the preparation of such compositions suitable for use as a lubricant or lubricant additive wherein components (1) and (2) are reacted in the presence of an effective amount of a polymerization inhibitor and/or in the absence of oxygen.
