A process for making a modified polyolefin in which an isocyanate of formula (1), wherein R1, R2, R3 and R4 are independently cyclic, straight or branched chain alkyl or alkylene groups optionally containing nitrogen, oxygen, sulphur or phosphorus heteroatoms, m is an integer between 1 and 10 and n is an integer between 1 and 100; is added to a feedstock polymer in a reactor heated to a temperature at which said isocyanate reacts with the feedstock polymer, the amount of the isocyanate added to the reactor being controlled to control the properties of the modified polymer. |
