A grafted polylactic acid is provided, wherein the grafted polylactic acid contains carboxylic acid end groups in an amount from 1.0 to 10.0 mg KOH/g and contains epoxide groups in an amount from 0.005 to 0.500 mmol/g.

Grafted polylactic acid

A composition is provided comprising an epoxide functional polymer comprising epoxide functional groups, wherein the epoxide functional polymer has a number average molecular weight of 1000 to 10.000 g/mol and a grafted polylactic acid, wherein the polylactic acid is grafted with an acid-functional ethylenically unsaturated polymerizable monomer and/or an acid anhydride-functional ethylenically unsaturated polymerizable monomer and has a total amount of carboxylic acid groups and carboxylic acid anhydride groups between 10.0 and 60.0 mg KOH/g.

Composition comprising a grafted polylactic acid

The invention relates to the use of a silyl functional compound b), which silyl functional compound comprises a N&#x2014;O&#x2014;Si bond, for improving the flame retardant properties of a composition comprising an organic polymer a), which is one of a thermoplastic polymer or a thermoset polymer or a mixture thereof.

Silyl functional compound for improving flame retardant properties

The invention relates to a composition comprising an organic polymer, and a silyl functional compound comprising a N&#x2014;Si bond.

The invention relates to a composition comprising a) a thermoplastic matrix polymer based on one or more ethylenically unsaturated polymerizable monomer(s), wherein the thermoplastic polymer is selected from the group consisting of polyolefins, polystyrene, polyacrylates, ethylene-vinylacetate copolymer, and copolymers and blends of the aforementioned, b) an inorganic flame retardant, c) a polymer based on one or more ethylenically unsaturated polymerizable monomers and having a plurality of alkoxysilane and/or acetoxysilane groups covalently linked to the polymer, wherein the ethylenically unsaturated polymerizable monomers of component c) are different or have a different composition than the ethylenically unsaturated monomer(s) of component a) and d) a clay.

Thermoplastic composition having improved flame retardant properties

The invention relates to a process of preparing a polyolefin polylactic acid polymer blend comprising the steps of i) providing a polyolefin selected from polyethylene, polypropylene, and mixtures and copolymers thereof, ii) providing polylactic acid, iii) providing a polyolefin selected from polyethylene, polypropylene, and mixtures and copolymers thereof grafted with at least one epoxide-functional monomer, iv) providing a polylactic acid grafted with at least one carboxylic acid or carboxylic anhydride functional monomer, v) mixing the components i) to iv) at elevated temperature in a range from 150&#xb0; C. to 260&#xb0; C., and wherein component i) is provided in an amount of 5.0 to 50.0% by weight, component ii) is provided in an amount of 40.0 to 90.0% by weight, component iii) is provided in an amount of 1.0 to 20.0% by weight, and component iv) is provided in an amount of 1.0 to 15.0% by weight, calculated on the sum of components i) to iv).
