Silicon modified vinyl acetate ethylene copolymer
The present invention relates to silicon-modified vinyl acetate ethylene copolymers, and to emulsions, articles of manufacture, and cement waterproofing compositions based on the copolymers. The silicon modified vinyl acetate ethylene copolymer includes: (i) 60 wt% to 95 wt% of vinyl acetate units; (ii) 0.1 wt% to 35 wt% of ethylene units; and (iii) 0.1 wt% to 5 wt% of units derived from the silicon compound of formula (I); wherein R1 is an alkenyl group with an unsaturated terminal; and R2, R3, and R4 are each independently selected from the group consisting of hydrogen, an alkyl group, a substituted alkyl group, a heteroalkyl group, a substituted heteroalkyl group, a cyclic group, a substituted cyclic group, a heterocyclic group, a substituted heterocyclic group, an aryl group, a substituted aryl group, a heteroaryl group, and a substituted heteroaryl group; the silicon content of the vinyl acetate ethylene copolymer bonded to the silicon modification is 0.06 wt% to 0.29 wt%.
本发明涉及硅改质的乙酸乙烯酯乙烯共聚物，且涉及基于该共聚物的乳液、制造物件以及水泥防水组合物。该硅改质的乙酸乙烯酯乙烯共聚物包括：(i)60wt％至95wt％的乙酸乙烯酯单元；(ii)0.1wt％至35wt％的乙烯单元；以及(iii)0.1wt％至5wt％的源自式(I)硅化合物的单元；其中，R1是末端不饱和的烯基；以及R2、R3及R4各自独立选自氢、烷基、经取代的烷基、杂烷基、经取代的杂烷基、环基、经取代的环基、杂环基、经取代的杂环基、芳基、经取代的芳基、杂芳基及经取代的杂芳基所组成的组，以及其中，键合至所述硅改质的乙酸乙烯酯乙烯共聚物的硅含量为0.06wt％至0.29wt％。
