Abstract
Fluorine-free small molecule additives of structure where X1 and X2 are independently hydrocarbyl or heterohydrocarbyl; and Q and Q are independently —Si—(O—Si(CH3)3)3 or —(O—Si(CH3)2)n—O—Si(CH3)3 and where n is an integer from 0 to 30, inclusive for use in solid-state formulations, e.g., thermoplastic articles, for use in low hysteresis water repellent applications. Methods of preparing such compositions and additives.
Claims18
A melt additive compound represented by the general formula
- wherein:
- X1 and X2 are independently hydrocarbyl or heterohydrocarbyl wherein X1 and X2 are independently —(CH2)n— and wherein n is an integer from 1 to 18, inclusive;
- and
- Q1 and Q2 are independently —Si—(O—Si(CH3)3)3 or —(O—Si(CH3)2)n—O—Si(CH3)3 wherein n is an integer from 0 to 30, inclusive.
(canceled)
A composition comprising:
- a thermoplastic polymer;
- and
- an additive represented by the structure
- wherein:
- X1 and X2 are independently hydrocarbyl or heterohydrocarbyl;
- and
- Q1 and Q2 are independently —Si—(O—Si(CH3)3)3 or —(O—Si(CH3)2)n—O—Si(CH3)3
- wherein n is an integer from 0 to 30, inclusive.
A method of preparing a composition, the method comprising:
- combining a thermoplastic polymer with an additive to provide the composition, the additive represented by the structure
- wherein:
- X1 and X2 are independently hydrocarbyl or heterohydrocarbyl;
- and
- Q1 and Q2 are independently —Si—(O—Si(CH3)3)3 or —(O—Si(CH3)2)n—O—Si(CH3)3
- wherein n is an integer from 0 to 30, inclusive.
