TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The renewable raw materials are plant materials comprising sugar cane and beet sugar, maple, date palm, palm sugar, Sorghum, American agave, corn, wheat, barley, rice, potatoes, cassava, sweet potato, seaweed or materials comprising cellulose or hemicellulose such as wood, straw or paper.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The composition comprises at least one additive comprising antioxidants, UV protection agents, implementation agent, anti-fog agent, antiblocking agent, filler, coupling agents, crosslinking agents, antistatic agents, nucleating agents, pigments, dyes, plasticizers, thinners or flame retardant additives.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: At least part of the carbon atoms of the unsaturated carboxylic acid or its derivative is from renewable sources. The unsaturated carboxylic acid is (meth)acrylic acid; 1-24C alkyl (meth) acrylate, preferably methyl acrylate, ethyl acrylate, n-butyl acrylate, isobutyl acrylate, 2-ethylhexyl acrylate; anhydrides of unsaturated carboxylic acid comprising maleic anhydride, itaconic anhydride, citraconic anhydride or tetrahydrophthalic anhydride; unsaturated epoxides comprising esters and aliphatic glycidyl ethers such as allyl glycidyl ether, vinyl glycidyl ether, maleate and glycidyl itaconate or acrylate and glycidyl methacrylate; or esters and alicyclic glycidyl ethers such as 2-cyclohexene-1-glycidyl ether, cyclohexene-4,5-diglycidylcarboxylate, cyclohexene-4-glycidyl carboxylate, 5-norbornene-2-methyl-2-glycidyl carboxylate and endocis-bicyclo (2,2,1)-5-heptene-2,3-diglycidyl carboxylate. The copolymer is: statistical copolymers of ethylene and methacrylic acid, statistical copolymers of ethylene and acrylic acid, statistical copolymers of ethylene and methyl acrylate or statistical copolymers of ethylene and butyl acrylate; statistical copolymers of ethylene and maleic anhydride or statistical copolymers of ethylene and glycidyl methacrylate; or statistical terpolymers of ethylene, butyl acrylate and maleic anhydride, statistical terpolymers of ethylene, methyl acrylate and maleic anhydride and statistical terpolymers of ethylene, methyl acrylate and glycidyl methacrylate. Preferred Process: The copolymerization step is a high-pressure radical copolymerization carried out by introducing ethylene, or comonomers and polymerization initiator in a high pressure autoclave reactor at a temperature of 150-290 degrees C, where the amount of comonomers introduced has up to 20 wt.% relative to the total ethylene and comonomers introduced into the reactor. The copolymerization step is high-pressure radical copolymerization carried out by introducing ethylene, or comonomers and a polymerization initiator in a high pressure tubular reactor at a temperature of 80-325 degrees C, where the amount of comonomer introduced has up to 20 wt.% relative to the total ethylene and comonomers introduced into the reactor. The mixture of ethylene and comonomer is injected at least another point in the reactor, where the injection is followed by another injection of initiator or mixture of initiators. The copolymer is grafted by polyamide or polyether blocks carrying at least one amino terminal function. EXAMPLE - Ethylene (12 tons/hour) and vinyl acetate (800 kg/hour) were introduced in a reactor. The mixture was compressed in hyper compressor at 2400 bar. The mixture was heated to 120 degrees C and Luperox 11 (RTM: Tert-butylperoxypivalate)/Luperox 26 (RTM: Tert-butylperoxy-2-ethylhexanoate) mixture was injected. The temperature was raised to 210 degrees C and then decreased to 160 degrees C.Luperox 11 (RTM: Tert butylperoxypivalate)/ Luperox 26 (RTM: Tert-butylperoxy-2-ethylhexanoate) mixture was reinjected. The temperature raised to 210 degrees C and then decreased to 160 degrees C to obtain 1.9 tons/hour of ethylene copolymer/butyl acrylate with a butyl acrylate content of 30 wt.% and a melt index of 2.
