1. A multiblock copolymer comprising at least one PA block, at least one PB block, and at least one PC block, wherein PC block is positioned between PA block and PB block, wherein PC block is a rubber block, and wherein PA represents a polymer block comprising one or more units of monomer A, PB represents a polymer block comprising one or more units of monomer B, and PC represents a polymer block comprising one or more units of monomer C, with monomers A and B being the same or different,
wherein the monomer A is selected from the group consisting of L-lactic acid, adipic acid, ethylene glycol, terephthalic acid, dihydromuconic acid, benzene-1,4-dicarboxylic acid, glucose, glycogen, galactose, silk, glycerol, 1,6-diaminohexane, and 1,4-diaminobenzene;
wherein the monomer B is selected from the group consisting of L-lactic acid, styrene, α-methyl styrene, t-butyl styrene, vinyl xylene, vinyl naphthalene, vinyl pyridine, divinyl benzene, methyl acrylate, methyl (meth)acrylate, ethyl (meth)acrylate, propyl (meth)acrylate, butyl (meth)acrylate, heptyl (meth)acrylate, hexyl (meth)acrylate, acrylonitrile, adiponitrile, methacrylonitrile, butadiene, isoprene, and mixtures thereof;
wherein the monomer C is selected from the group consisting of styrene, α-methyl styrene, t-butyl styrene, vinyl xylene, vinyl naphthalene, vinyl pyridine, divinyl benzene, methyl acrylate, methyl (meth)acrylate, ethyl (meth)acrylate, propyl (meth)acrylate, butyl (meth)acrylate, heptyl (meth)acrylate, hexyl (meth)acrylate, acrylonitrile, adiponitrile, methacrylonitrile, butadiene, isoprene, and mixtures thereof; or
wherein the monomer C is a radically polymerizable glycerol derivative; an acrylated epoxidized triglyceride; an acrylated glycerol; an acrylated epoxidized soybean oil (AESO); or a radically polymerizable plant oil monomer selected from the group consisting of soybean oil, corn oil, linseed oil, flax seed oil, and rapeseed oil.
