Abstract:
1. A composition which comprises an end cap crystalline (ECC) polymer and a release material associated with the ECC polymer, the release material being (1) one or more bioactive materials which are useful in agricultural applications and which are selected from the group consisting of fertilizers, biocides, insecticides and fungicides or (2) one or more additives which are useful in personal care compositions and which are selected from the group consisting of UV absorbers, fragrances, biocides, antimicrobial agents, germicides, antioxidants, preservatives, disinfectants, enzymes, nutrients and minerals, wherein the ECC polymer (A) comprises a plurality of polymeric molecules each of which consists essentially of wherein each terminal unit having formula (2) is a moiety selected from the group consisting of (B) has a crystalline melting temperature, Tp, of at least 0° C. and a heat of fusion, ΔH, of at least 3 J/g which result from association of the Cy moieties, Tp and ΔH being measured on a differential scanning calorimeter.
