    Abstract: A method of crosslinking polystyrene polymers and co-polymers for the formation of macroplegmatic materials of an Mc 30,000 to 50,000 is described. The materials forming an insoluble gel which is shaped in an extruder to 3 to 5 cm pieces and is subject to sulphonation with dense sulphuric acid, with oleum sulphuric acid with sulphur trioxide and with chlorosulphonic acid, and the introduction of sulphonic groups to a high density and with the introduction of nitric group and with the introduction of carboxylic group with the copolymer styrene-acrylonitrile. The chlorosulfonic group promotes sulphonation and crosslinking with the formation of bridges with the sulfone group which is controlled with a 10-20 % of acetic acid present as regulator and an insoluble volume of gel is formed which following drainage of the solvent and after remaining to ripen for 4-7 hours it is treated with ethanol or propanol to extract the unreacted chlorosulphonic acid then is neutralised with sodium or potassium hydroxide subjected to an extruder for the preparation of 3-5 cm products. Following neutralisation and shrinkage to a 10 % water content and the products produced are deodorised at a temperature of 160 DEG C under vacuum and are converted to materials which absorb water inside their molecules up to 300 times their weight; having an inorganic content of 72-75 % they exhibit a high degree of stability in the ground, they do not degrade and can be used indefinitely for water absorption-release so that they operate as fertility promoters to any type of soil leading to an increase of green growth, and to the planting of trees and forests and to advance food production.

    Abstract: The invention relates to a process for producing polymer-polypeptide conjugates with reduced immunogenicity comprising the steps of: a) generating a polymer halogen formiate; and b) conjugating at least one polymer-halogen formiate to at least one attachment group on the polypeptide (Pep). The invention also relates to a polymer-polypeptide conjugate with reduced immunogenicity, an activated polymer for conjugating polypeptides (Pep), and the use of said process for reducing the immunogenicity of polypeptides used for pharmaceutical and/or industrial applications. Finally it is the object of the invention to provide the use of said polymer-polypeptide conjugate for a number of therapeutic and industrial purposes, such as the use in pharmaceuticals, personal care products and detergent compositions.

    Abstract: A process for producing a polyolefin having a terminal functional group in an industrially advantageous manner, comprising the step (A) of producing a terminally modified polyolefin of the general formula P-AlR R (wherein P represents a polymer chain, and R and R represent each a C1-C10 hydrocarbon group, etc.) in the presence of an olefin polymerization catalyst prepared from a solid titanium catalyst component (a), an organoaluminum compound (b), and optionally an organosilicon compound (c) and the step (B) of either conducting a substitution reaction between the -AlR R group of the polyolefin obtained in the step (A) and a compound having a functional structure, or conducting a substitution reaction between the -AlR R group of the polyolefin obtained in the step (A) and a compound having a structure capable of forming a functional group by solvolysis, followed by the solvolysis of the reaction product to yield a polyolefin of the general formula P-X (wherein P is as defined above, and X represents a functional group). The obtained polyolefin is useful as, for example, a compatibilizer for polymer blends and a starting material for molecular design.
